Allowed po ba iprocess dito sa Australia yung application nya?
Yes. You should apply for Visa 101 - child should be outside Australia during application and grant.
Need pa po ba kumuha ng consent sa biological father nya even inabandon sya since 9 months sya at no communication or anything sa tatay hanggang ngaun? Merun po kami dito affidavit of abandonment nung kinuhanan namin sya ng passport.
Were you married to the biological father and Is the child using his last name? if so, Yes. you need to secure his consent by completing form 1229

If you were not married, regardless if the biological father is named on the child's birth certificate, you can submit an affidavit of sole parental authority then include your affidavit of abandonment.
Hope this helps. All the best!
