4WD Supacentre is the home of Adventure Kings outdoor and 4WD products. Place to get budget conscious supplies of camping gear.  Some stuff can be hit and miss, but know what you're getting for the price you're paying.   Lots of daily specials, and be sure to shop around and never pay 'full' price.

CUTTING THE COST OF QUALITY TIME IN THE GREAT OUTDOORS
4WD Supacentre's company store network is growing rapidly with almost 20 across all mainland states and territories except NT. From Townsville to Melbourne and across to Perth, the majority of Australia's population lives close to a 4WD Supacentre store.

Established in 2012 by the Vella family, Adventure Kings range of outdoor products has been sold through 4WD Supacentre stores where you can touch and feel the quality for yourself before you buy. At 4WD Supacentre all popular products are on display in fully stocked showrooms, and our staff are as passionate about the outdoors as you are and able to help with expert advice on anything from battery and solar questions to LED lights, camping setups and vehicle fit-outs.
