Life insurance

I became a dad about 9 weeks ago and having the best of times. Was up late last night unable to sleep and got thinking about life insurance, we have a mortgage, both have decent jobs but very little left in savings after securing the apartment. I’m sure there’s a clause in the mortgage that if one of us pass the mortgage is void but want to ensure we’re covered by all angles. Has anyone got any experience in this, what should we be looking at with a newborn? Interested to see what overs have done. TIA

Edit: I live in Australia if that helps
