Live in Adelaide,
Nice little place… city can be sleepy at times but depends what you want? Bars and places to eat are around but finding the better ones can prove difficult..
Wine tasting is a must! really I can’t stress this enough. Barossa is an hour and 15 away from the city, the hills are more spread out so you’ll get to less and the M’Vale is an hour away from the city.
All have great wine. You could get a tour on the saturday and then chill at the beach on the Sunday. I’d avoid the beach at Glenelg due to being busy and from my experience… dirty aka dog eggs, cig-butts etc. It’s certainly still better than most in the UK. I’d suggest Grange, (train can get you here or a short bus trip from Glenelg up the coast. Henley & West Beach are great too.
You can walk to the zoo from the city or hire a car and drive to Gorge wildlife park in the hills

Lots of options – give us more detail and I’ll try and give you ideas and info.
Also Zokes is away from memory…. he forgotten what a bike looks like the lads that busy!
Regards
Scott.
