Husband sends $1000 to his family every month

My husbands family (parents and siblings) live in a country where there are no jobs currently because of political turmoil and war. My FIL was the sole source of income but he is out of work now.

My husband and I live in Australia and we are renting. We have a toddler and I just started casual work a month ago. My husband has his own small business which is doing ok, but he’s now taken up Uber driving additionally.

My husband has been sending his family $1000 every month. I don’t want to say anything to him as I don’t want the fight. But yesterday my mum asked me how much he sends and when I told her she was shocked and angry. She said his family is being unfair asking for so much money every month. I was really upset too. Do you think it’s really excessive? How would you go about the situation without causing a huge fight.

Keeping in mind we plan on purchasing a house sometime this year. I’m feeling so down knowing my in laws are just taking all this money from my husband and not even caring about our own situation.

Update: my mother in law has been spending a lot of the money buying fancy clothes and jewellery for her daughters. I have done research and have found that $300 is enough for utilities, food, water, clothing. Also my in laws own their own house and plenty of land with vegetation. Just wanted to add that info for the people judging me about being upset that my husband was working two jobs in order to support them while they use that money for silly things.
