Form 1445 WHV extension

[Meg7 1]

Hello everyone, 

I have applied for my spousal 820 visa and everything has been submitted successfully. 

I am looking at sending form 1445 of for an extension from my WHV to my bringing visa. I have a 4 week gap. 

Can anyone tell me what email to send this to as it doesn't actually say. 

And how quickly I’m i likely to hear from anyone. 

Thanks :)
