Group Case Break advice / Is it ok to do? Admin advice needed

Hi guys
Just need a quick bit of info please -
Is it ok to do Group Case breaks on Ozcard and what are the rules please? A few of us are interested in breaking a case of Topps Premier Gold but are unsure if Ozcard allow it. There have been quite a few on Blowout (US) and FCF (UK) and they seem to work really well.
If we could please get some advice from a Moderator it would be much appreciated.

Cheers
Dylan
