No you cannot play games on consoles made for different regions. You can only play games on the consoles made for a specific region. If you attempt to play games cross region it will simply not play.
If Australian games are the region PAL then yes.
yes you can because Australian ps3 games are PAL, AU,NZ,UK so you can play games from UK on your Australian console i have heaps of UK games that i have purchased of the internet and they work just fine on my Australian ps3
yes you can i have many format 2 games that play on my Australian ps3

No. Wii consoles are locked by region and can only play games bought in the same region as the console. Games from the US and Europe cannot legally be played on a Japanese console.
all PS3 Products will work where ever you are.
if the game and console are PAL it should be alright and i think the UK and Australia are both PAL regions so it will probably work
