I bought a new raspberry plant this weekend from the Ferny Grove markets. I sent the last one up to Toowoomba where I hope the frost will help it fruit better, as I was having no luck with it.
The advice I got from the grower was that raspberries in Brisbane need to be the non-frosting kind. I bought a Bogong, but he was also selling Autumn Bliss. He said you can grow your raspberries on a trellis, and pinch out the tips if you want to grow it as an espalier.
We did get some fruit on our native raspberry but not enough to make a meal of them. You can buy them from Northey Street.
