Hi guys! I hope everyone is well!

I am in need on some impartial advice. My husband, 2 year old son and I have possibly been offered an employment visa to enter Australia. We are currently living in Zimbabwe, both running our own small business and doing quite well - however - my whole family is in Aus and UK. We also feel Zimbabwe has little to offer our son In his later years... however we are both able to spend as much time with him as we like at the moment whereas in Australia I would be working an 8 - 5 job and obviously have far less time with him. Has anyone here immigrated to Australia and what are your thoughts/feelings? Any advice is welcomed!!!
