Hey Steve
we are living in Redcliffe which is half an hour from Brisbane so work anywhere either way from my house within half an hour, yes you need a white card and to get the white card do it online with Bluedog training, that is who I did mine with and it was straight forward, tape and joint on site is $900 for a house and I can do one in 2 hard days so 2 men could do it in the day, it's all done using boxes over here, but as I've said before I want to board and they glue boards on over here with screws at the top and bottom of a board and that's it, they also board side ways over here not upright like in the UK.
