Hi, and welcome to a place where none of us think we'll end up. It's all a whirlwind at the start, but it sounds like you're well on the way to a plan.
We're all different in how we react to chemo, and there are a number of different combinations. A lot will depend on what you have, and how you react. You really won't know until you start.
I did manage to work 3 days a week through chemo, working Monday, Wednesday & Friday. I had a very supportive workplace, and was able to take breaks for a rest if I needed. They also arranged a work laptop so I could work from home if I couldn't come in.
It's worth looking in to whether you have income protection with your superannuation, as this may prove helpful, although there are lots of conditions around its use, @Sister & @melclarity may be able to help with that.
I'm sure @SoldierCrab will also be along to help with some useful tips for navigating the forum.
You will find lots of support here, we also have a few good laughs at times, along the way
Take care
