My partner's superannuation is low

Who wants to be average?

Exactly, keep feeding your super. If you can aim for 80% of your gross income from super (use the calculator on your Superfund website) , you'll be laughing. IP income will be a bonus.

 

$150k at 30
$300k at 40
$600k at 50
1200k at 60
2400k at 70
cBus over 39 years has returned better than above growth. Even with no more contributions and taking inflation into account your retirement will be comfortable.

$150k at 29 is heaps

 

My body will be stuffed in 10+15 yrs though. I want to be a stay at home dad when we can figure out how to make a child, wonder what it'd do if I left it at 250k

 

Lots wiser people than me.
Your Super looks sorted even with minimal contributions for another 10 or 15 years.
I would be investing spare money outside Super to FIRE
Owning a home outright at retirement is a good idea too

 

We've just bought a second house so debt reduction is the next step. PPR is 200k off being paid off, I was hoping by 30 we'd be debt free but came here and subsequently bought an IP instead! We're pretty boring people when it comes to spending money, I laugh when our highest weekly spending is donations. We got zero financial help from our parents other than a good stable home life.
