Bosch Professional GET 75-150 Random Orbit Sander (750W, 150mm)
Our Verdict
The best finish-sanding machine you can actually buy on Amazon AU today - a 750W corded pro random orbit whose active pad rotation strips stock like a rotary and then finishes like an orbital.
The GET 75-150 is Bosch's flagship corded random orbit sander and it is the tool to buy when sanding is the job rather than a step in the job. The 750W motor is roughly triple what a cordless 125mm sander puts out, and the switchable active pad rotation is the party trick: turn it on and the pad is driven rather than free-spinning, which rips through paint, filler and rough-sawn timber at a rate no battery sander here gets close to; turn it off and the same machine drops back to a conventional 4.5mm-orbit finish sander. The 150mm multi-hole pad takes any brand of hook-and-loop disc regardless of hole pattern, so you are not locked into Bosch abrasives, and the variable speed dial (3,300-7,300 rpm) lets you wind it back for lacquer and plastics. The front palm rest and slim body genuinely help on a long day of vertical work. Note: this is a UK-import listing shipped by Amazon UK - it is a 230V tool, which is correct for Australian mains, but it arrives with a UK plug, so budget for a plug swap or an adaptor, and warranty is handled through the import channel rather than Bosch Australia. It replaces the Festool ETS EC 125/3 in this slot, which now only lists on Amazon AU as a six-to-seven-month backorder at more than double its real price.

The DBO180Z is the most-recommended sander on the LXT platform for Australian cabinetmakers and renovators - compact, lightweight (1.7kg), and built on the largest professional cordless ecosystem in the country. A 2.8mm orbit is genuinely fine-finish territory, the 7,000-11,000 OPM variable speed dial gives proper control across timbers and finishes, and the dust extractor port accepts standard Makita 22mm/24mm and 28mm/38mm hose ends. Brushed motor is the main concession against the premium tier - for the price, it's the easiest entry into a serious cordless sanding setup if you already own LXT batteries.

The GSS 18V-10 is the right pick when you want a finishing sander rather than a random orbital - flat 1/4-sheet rectangular pad for large flat panels (doors, shelves, table tops), 1.6mm tight orbit for absolutely swirl-free finish coats, and three interchangeable base plates so you can switch between standard, delta-edge, and curved profiles in seconds. Built on the Bosch Pro 18V platform that cross-fits batteries from 2008 onwards. Worth pairing with a random orbital - these are complementary tools, not substitutes, and a finishing sander earns its keep on any cabinetry or door-rebuild job.

The BOS125 is Milwaukee's answer for the M18 user who doesn't want to drag a power lead onto a job site. A POWERSTATE-style brushless motor delivers 7,000-12,000 OPM, the variable-speed dial gives genuine fine control for finish coats, and the dust canister twists off cleanly for emptying without the swarf shower most onboard bins produce. The biggest win is platform fit - if you already own M18 batteries, this is the cheapest path into pro-tier cordless sanding. Connect it to a Milwaukee PACKOUT M18 extractor for near-shop-grade dust capture without a power lead.

Bosch's GEX 18V-125 is the smart pick if you already own Bosch Pro 18V batteries - the brushless motor matches corded performance on most jobs, the anti-vibration handle genuinely reduces hand fatigue on long runs, and the 35mm hose port is the most universal extractor fitting in the trade. Pad orbit is the 'Bosch sweet spot' (4mm) that splits the difference between Festool's finishing-focused 3mm and Milwaukee's aggressive 4.8mm - fine for finish, fast enough for stock. Microfilter onboard box catches the worst of the fines for short runs; for anything past 15 minutes, run a vac hose.

The DCW210B is the most popular brushless random orbital on the DeWalt XR platform - high 12,000 OPM ceiling for aggressive stock removal, sensible 8,000 OPM minimum for finish coats, and a rubber overmold grip that's noticeably more comfortable than the older brushed DeWalt sanders. The one-handed locking dust bag is a nice touch for jobs where you can't run a hose. As with several DeWalt models on Amazon AU, this is a US-spec import (20V MAX = 18V XR battery-wise), so verify the seller's warranty terms before pulling the trigger if local AU warranty matters to you.

Ryobi's RROS18 is the cheapest credible cordless random orbital on Amazon AU, riding the back of the 250+ tool ONE+ ecosystem that already lives in half the sheds in Australia. Single-speed brushed motor and a basic onboard dust bag put it firmly in DIY territory - but for a deck refresh, a weekend furniture project, or the occasional door rub-back, it delivers genuinely usable results. 125mm pad pattern accepts standard 6-hole and 8-hole abrasives from any AU hardware store. If you're already on ONE+ for the drill and impact, adding this skin is a no-brainer; if you're shopping cold, factor in another A$120+ for a battery and charger.

We score random orbital and finishing sanders across four category-specific dimensions: Removal Rate (motor wattage or unit watts out, orbit diameter, OPM under load), Finish Quality (pad balance, vibration, variable speed range, swirl-free performance on hardwoods), Dust Management (onboard bin sealing and extractor-hose port quality), and Value (kit completeness and platform fit vs price tier). Specs come from manufacturer data, cross-checked against Pro Tool Reviews, Tools In Action, Australian Wood Review, and AU retailer listings (Sydney Tools, Total Tools, Tool Kit Depot). We only rank tools readily available on Amazon Australia with reasonable shipping.
Scored 0–10 on Removal Rate, Finish Quality, Dust Management, Value
Random orbital sanders (125mm or 150mm round pad with an offset bearing) are the modern default - fast stock removal plus swirl-free finish thanks to the random orbit pattern, and they handle 95% of timber and finishing work. Finishing sanders (rectangular 1/3 or 1/4 sheet pad, pure orbital motion) are slower at removal but excel at flat, large surfaces and accept standard sandpaper cut to size. Detail sanders (triangular pad, often called mouse sanders) are for corners and tight inside angles only - fine as a third sander, never as your primary.
Cordless vs Corded
Cordless 18V brushless sanders (Bosch GEX 18V-125, DeWalt DCW210, Makita DBO180, Milwaukee BOS125) now match corded performance for short-to-medium runs and free you from a power lead. Corded sanders still win on long sustained jobs - a deck, a kitchen full of cabinet doors - because there's no battery limit and no thermal cycling. If you'll sand for more than 30 minutes at a stretch, keep a corded backup; otherwise the cordless ecosystem fit usually wins.
Dust Extraction: Hose vs Onboard Collection
This is the dividing line between hobbyist and pro. Onboard dust bags or canisters work for 5-10 minutes before they choke and reduce suction by 60%. Connecting a vacuum or M-class extractor via the hose port (35mm or proprietary on Festool/Bosch) drops airborne dust by 90%+ and keeps the disc cutting at full rate. If you're sanding indoors, near a finish coat, or for more than 15 minutes at a stretch, run a hose. Most modern 125mm pads have multi-hole punching (8-hole, 6-hole) that aligns with extractor flow paths.
Variable Speed
A variable-speed dial (typically 4,000-12,000 OPM) matters more than peak speed. Lower speeds for finishing coats, paint stripping, and softwoods (where high heat burns the surface or melts paint into the abrasive); higher speeds for hardwood stock removal. Single-speed budget sanders force compromise - fine for one material at one stage, frustrating across a real project.
Pad Size & Grit Compatibility
125mm round pads are the modern standard - wide enough for good coverage, small enough for tight work, and every premium abrasive brand (Mirka Abranet, 3M Cubitron, Festool Granat) makes 125mm discs in 6-hole and 8-hole patterns. 150mm pads remove faster on large flat panels but are clumsy on edges. For finishing sanders, 1/3 sheet is the workshop default; 1/4 sheet is lighter and one-handed. Always confirm your disc punching matches the sander's hole pattern - mismatched holes ruin extraction.
Sanding is the slowest, dustiest, and most-skipped step in any finishing job - and it's also the one that decides whether your project looks like a furniture maker built it or whether it looks like a weekend warrior had a go. The single biggest separator between hobbyist tools and pro tools in this category isn't motor power or pad size: it's dust management. A pro-tier random orbital paired with an extractor will leave the air around you breathable and your timber primed for finish; a budget skin with an onboard dust bag will choke on its own swarf within minutes and bury your workpiece in clag.
The Amazon AU listings now carry the full pro lineup - Festool ETS EC, Milwaukee M18 FUEL BOS125, Bosch Professional GEX 18V-125 brushless, DeWalt DCW210 - alongside the popular value-tier skins from Makita LXT and Bosch's 18V finishing platform, and a credible Ryobi ONE+ budget option. The question for most Australian buyers isn't which brand makes the best sander; it's whether you'll commit to running an extractor hose at all. If yes, a 125mm random orbital from any of the four pro platforms will outlast the user. If no, prioritise tools with the largest, best-sealed onboard collection bin you can find.
We've ranked the seven sanders Australian buyers should actually consider on Amazon AU in 2026, split across Premium (pro-tier dust extraction, brushless motors, hose-ready), Best Value (the brushless and corded sweet spot at A$150-A$300), and Budget (DIY-grade tools under A$150). Specs are triangulated against manufacturer data, professional reviews from Pro Tool Reviews and Tools In Action, and current Australian retailer listings - always confirm against the live Amazon AU listing before purchase.

Random Orbital & Finishing Sanders — Frequently Asked Questions
Random orbital or finishing sander - which should I buy first?+
Random orbital, every time. The random orbit pattern means you get fast stock removal AND a swirl-free finish from the same tool, and 125mm round abrasives are available cheaply at any AU hardware store. Finishing sanders excel on large flat panels and accept standard sandpaper cut to size, but they're slower on removal and limited on curved or contoured work. Buy the random orbital first; add a finishing sander once you're regularly building cabinetry or doors.
How important is dust extraction?+
Honestly, it's the single biggest factor in whether you'll enjoy sanding or hate it. Onboard dust bags work for 5-10 minutes before they choke and your disc starts skidding instead of cutting. Connecting a workshop vac or M-class extractor via the 35mm hose port (or proprietary Festool/Bosch port) drops airborne fines by 90%+, keeps the abrasive cutting at full rate, and means you don't end every job with a clean-up that takes longer than the sanding itself. If you sand indoors or near a finish coat, run a hose - every time.
Will a cordless sander have enough runtime to sand a deck?+
Borderline. A 5.0Ah battery on a brushless 18V sander gives you roughly 45-70 minutes of continuous use under load - enough for one or two coats of a small deck but not a full strip-and-refinish. For large decks, a corded sander is still the smart choice (no thermal cycling, no battery cooldown breaks). For a typical 15-25 sqm balcony or veranda refresh, two batteries on rotation will get you through.
What grits do I actually need for timber work?+
For raw timber to finished surface, the standard progression is 80 grit (stock removal, flattening), 120 grit (intermediate, removing 80-grit scratches), 180 grit (final pre-finish for stain or oil), then 240 grit (between coats if applying polyurethane). For paint stripping or rough work, start at 40 or 60 grit. Don't skip more than one grit step - you'll spend longer trying to remove the deeper scratches than you saved jumping ahead.
Festool vs Mirka - is the premium worth the money?+
If you sand for a living, yes. Festool's pad balance and dust extraction are genuinely class-leading, the 36-month warranty on registration is the best in the trade, and the Systainer storage ecosystem keeps a workshop organised. Mirka DEROS (a direct competitor) trumps even Festool on weight and vibration but is harder to find on Amazon AU. For a weekend hobbyist or even a regular renovator, a brushless cordless from Milwaukee, DeWalt, Bosch Pro, or Makita LXT will produce 95% of the same finish at 40-50% of the cost - the Festool premium pays off mainly for users who run the tool 4+ hours every day.
Should I get a 125mm or 150mm pad?+
125mm is the right choice for almost everyone - better balance, lighter, easier to control on edges and curves, and abrasives are universally available in 125mm 6-hole and 8-hole patterns. 150mm pads remove stock faster on large flat panels (kitchen bench tops, table tops, wide doors) but feel clumsy on smaller furniture work. Most pros own both; if you only buy one, start with 125mm.
