I actually ended up using them before I read your post , $77 plus import stuff , I'm sure many do it themselves which you surely can but the hoops and timeframe I could see lining up quickly past the $77
Sent info last night released to aus post by 11,00 am today still havn't heard from customs by mail, i rang aus post with tracking no who put me through to get a customs referance no as thats all you need.
