Edit - madtuna beat me to it!!
It just takes planning and organisation.
I keep a lot of my camping stuff in tubs in the garage, and just put them straight in the ute when it's time to go.
Organise stuff into groups to make it easy to unpack at camp.
Eg. The first thing you do is set up a tent - so have everything for that in one tub.
1 tub - ropes/tent pegs/tarps/tools/tent
1 tub - cooking/kitchen stuff
1 tub - first aid/snake bite kit
1 tub - misc. torch/batteries/TP/pegs/repellent/sunscreen etc
1 backpack - panning gear
1 bag - clothes/toiletries/towel
1 tub - food and water
etc etc..
Have a list of individual things - esky, chair, table, bucket, shovel etc. that you keep all in the same area, to just load them up.
Have a list in each tub to check them off, if you take anything out of them.
Organisation makes it easier, and keeping things in tubs that you don't have to unpack at home, makes it easier to unpack the car too.
Just stack them in the corner of the garage and you're done!
Always keeping the system in place, also helps you to find things easily at camp, because you know exactly what tub they're in to find them quickly, rather than rummaging through everything to find something, which is a pain in the neck!
Have dedicated camping gear such as kitchen stuff, that you don't take from the house supply - keep it all in the tub.
Be organised - it makes it a lot less work to go camping!
