WE are also same like you. Can't expect immediate response from them..You can expect a Background Check for Applicant if it is started or not?
Usually BGC is a good sign but that also can take from week to months. Also if BGC started most cases; that happens only if they decide NO interview.but again we cant figure out exactly how they work! Your best bet is to WAIT and WAIT at least till MID JAN, let this Holidays season pass. And we'll see if any member in Canada gets updates from Sydney. Hope this is helpful
HAPPY NEW YEAR
