What to do?

I’ve recently returned back from Aus and making 70k plus commission. We don’t have a pension plan in place at the company currently.

In Aus I was getting 4.5% interest in my ING savings account so I didn’t make any investments.

I currently have €86k in my current account after bringing it back from Aus and have no clue what to do, the interest rates the banks here are offering me are laughable.

I was thinking of putting 10/15k into some ETFs an 10/15k into a pension pot and keeping the rest for a deposit down the line. But have no knowledge of investing really. Any advice is welcome….
