Upgrade bid Qantas domestic flight with points

[auspal]

We will be flying from Sydney to Hobart, can anyone tell me how many points I should bid to upgrade to business class please ? It will be Qantas 1534 thanks.

I wouldn't bid more than about 5000 points; if I were using cash $110-120 would be the limit of my largesse.

Looks like I I have to use cash as well as the 5000 points ?
