Home Affairs advice

Ok, first of all, If you have applied for a visa extension and you have a paper (acknowledgement of acceptance or something like that) with a date stamp on it, then she can stay in the country until you will get an official answer. If you DO have such paper, but DON'T have the reference number, call their toll free line, they will ask you your partner's passport number etc, and then they will give you the reference number. Currently there is huge back log regarding long term visa extensions. So, yeah, as long as you managed to apply for extension or new type of visa before the current one is expired, she doesn't need to leave the country until you will get the official answer.

Seems like you were correct, a relative confirmed this on my behalf with the DHA.... so now a little more relaxed.
