I am 60yrs old and working full time.
If I invest $50k into my super am I able to access it before my planned retirement at 65?

Hi Bruce,
As you are over 60 and currently working all you would need to do is cease employment with an employer. So if you are currently just working full time for 1 employer, you would need to cease employment with that employer (change jobs or retire).

If you are making a lump sum contribution to superannuation, I would suggest fully utilising your concessional contribution cap ($25k per annum) before making non concessional contributions.

Cheers

Glenn
