Any Suggestions for my Increased Income and Savings Plan

All figures below in Australian dollars. Any advice would be appreciated.

34 years old working in business. I began working at my current company 8 years ago and pay has slowly progressed over the years. I am about to start a new role in December at the same company and finally getting a large pay increase.

Base salary 8,640.00 per fortnight before tax + 1k goes into my super.

5,880.00 after tax per fortnight
11,760 after tax per month after taxes

Current Expenses/
Mortgage = 2700/month
All bills roughly =1000/month
Food + other = 1k/month
No kids

The main drain of my previous income was travel. I realistically should have saved more earlier, but the memory dividends will last a lifetime. I am cutting out travel for a while to try and maximise savings. With travel gone, I will be able to save 7k a month, possibly more with a little overtime.

Property bought 4 years ago for 635k and have 560k remaining. One year remaining before I need to renew my mortgage currently at 3.29% fixed and planning to do an offset account after that. It has been appraised recently for about 750-800k.

Savings/
Super has been maxed out and I will continue to do so going forward.

50k emergency fund.

I used to do index funds but sold them to buy my first property.

Thank you for reading so far! My main question is:

1. I’m thinking of keeping all my money in my savings account and when I fall off the mortgage cliff in 12 months time I can have a decent amount for an offset account.

2. Alternatively, restart investing in index funds.

I am many years from financial independence, but I have become more serious about aggressively saving. Any advice is appreciated. Feel free to ask questions if you feel it can give you a more helpful advice.
