Hello Xenoviah, thanks for being here and understand what you are trying to cope with and sometimes the kids are able to sort out the problems between mum and dad, other times that's impossible because it may not have anything to do with the kids, so the parents need to come to an agreement or solve this problem the way they want it to be.
The money your dad sent over could be to help pay the bills your mum has incurred and for you to find a job just to help pay her bills is a big ask, simply because you don't know what they are or why she needs help as she is responsible for her own debts, although rent money may not be included in helping her, but you can let us now about this.
You are worried that with dad moving out is breaking the family tie and yes it's very much concerning because what they arguing about may not be serious, but because they continue to disagree it might be the final straw.
Perhaps you could suggest for them to contact relationship at 'https://www.relationshipsvictoria.com.au' and copy and paste this in your browser as there is an online form to fill out or there are different places you can contact them, best to have a look.
