Sorry to see you here, @NewBoobsPLS - welcome to the club that no-one really wants to join .... but you'll have lots of support & tips on getting thru this.
Try not to get too far ahead of yourself at this point in time & be guided by your medical team. Do you have a Breast Care nurse assigned to you yet? They are a mine of information. The biopsy gives a basic diagnosis - it is only after surgery & pathology that the team will discuss your long term treatment with more certainty. The surgeon often has a 'team' that he works with & is confident with - so chat with the surgeon first up.
Take a good buddy with you if you can - both for support AND a 2nd set of ears. Also, record your meetings on your phone, so you can review it later. It is almost impossible to remember everything that is discussed.
Going public with surgery & chemo/rad onc/Onc is very cost effective as it is almost free (going private can cost a lot, even if you have medical insurance.) So do your homework in the mean time, contact your private health insurance to see what you are covered for. I was out of pocket up to $6000 with 'gaps' from surgery & treatments prior to Rad Onc & Onc.
Whereabouts in SW Sydney are you ..... town/city? Members may be able to guide you towards services available there.
Take care & All the best for your results xx
