It looks like Vodafone is offering their 100Mbps premium plan for $69 per month for the first 6 months (save $20 per month).
No contract, though there is unfortunately a modem fee if you leave Vodafone within 36 months ($5 x remaining months). One pro of their modem is the 4G backup (Max speeds are 12Mbps for downloads and 1Mbps for uploads).
Typical Busy Speed 83Mbps. Fair Use Policy applies. Max modem cost $180. Total min cost $249. Offer ends 31/07/19. T&C apply.
Also keep the bundle discounts in mind, if already a Vodafone customer:
"Bundle eligible nbn™ plans, phone, tablet and mobile broadband to get from 5% to 20% off plan fees. T&C apply."
5% off each plan for 2 services
10% off each plan for 3 services
15% off each plan for 4 services
20% off each plan for 5 services
Edit: $50 cashback from Cashrewards (normally $30) - Cashrewards Expired
Update: Offer has been extended to 31 July.
Update: Offer has been extended again indefinitely (assuming to be the end of the year).

So there is a contract just not for the NBN part.
terrible deal.
