Getting back to Australia

Hi everyone, my name is Terrianne and I'm trying to get home to my daughter after a 2 week trip to America has turned into 5 months due to the corona virus. I missed my daughter's 16th birthday and mothers day with her that broke both of our hearts. I have listened to her struggles without me, and everyone  that know us, know how close we are and the devastating circumstances we are in.  
I have had 2 flights cancelled because they are putting business class as priority over economy travellers and the prices are astronomical. I have tried our Australian embassy and home affairs to no avail for help. Flights to Melbourne are not available as 6 week lock down. I'm happy to fly to sydney to stay with my sister and quarantine there then find a way back to Victoria. I NEED to get to my daughter as she now is on medication for depression and anxiety and talking to a therapist, nothing she needed before this virus took over. She needs her mother badly. 
The Australian government has stopped any payments to me so I'm not earning any income to be able to pay the flights that change every day more and more.  I don't know what to expect coming home , but all I need to think about is my beautiful girl I love so much missing her mum. 
I ask with my heart that you can help fund my trip home and know that I will be forever grateful.
