Offer popped up on Facebook.
Unfortunately for me weren’t great after they changed from Vocus in Sydney. I’m currently with Australia Post nbn and going well. So will wait, but tbh I don’t know if If would sign up to them due to speeds in Sydney.
If you are happy with them it’s very cheap for 6 months and says one month risk free
For 6 months $20 off:
25/5 $39
50/20 $49
100/20 $59
100/40 $69
250/20 $79
From the page offer
“ Our best internet offer ever
Sign-up for any MATE nbn internet plan and enter the exclusive promo code ACN20 at checkout, and you’ll save $20 off your internet plan for the first 6 months¹! Be quick, limited time offer”
I switched from Mate 250/20 to Spintel 100/20 and I think it's actually better in peak hours.
