What's the internet like in Coomera waters

It does really depend on which street and house you live in - I have suggested before anyone purchase/rent they ask for speed test etc - its the best way of knowing..

Its pretty good. We have a $500GB plan for 30Mbs for $95/month including line rental (for alarm system). TV reception is also via fibre so great picture.

Bad, people call the service with Pivit 'pivs#hit'

I thought this document would be of interest to you, it is a guide to communications for people building a new home in Coomera Waters.
