Sorry to jump in, but as someone who's considering up'ing sticks to Sydney and bringing a 2006 110 with them from the UK, whats this talk of "only 2 months into rego"???
Anything I need to be aware of? I have read posts on here and other sites about importing vehicles, but this seems new to me.
As for bulkhead change (that English) or Firewall change (Australian?) - Body off is officially the way to do it. If you have the means to lift the body then thats how I would do it. If not, unbolt roof, windscreen and front wings off. Unbolt and lift out (obviously seperating other bits first!).
