I was with Westnet for quite a number of years, but not having a landline here in the caravan park, I use the WiFi system. Its quite good and reliable (The owner is quite friendly, I'm the only one in the park with a permanent connection, no timed logoff
)
I kept a dialup service with westnet for a couple of years to retain my email address, ($12.50/month) until they called me since it was'nt being used, and offered a mailbox at $10/year. Good customer service, works for me.
