Best Australian web hosting company period.
I switched from other hosting companies to Relentless Hosting, due to the Australian datacenter location, service, and superior pricing plans. Specifically, the budget plan allows for 5 GB (I heard that they switched to SSD) storage, 5 hosted domains / emails, an app installer, and weekly backups.
The customer service is excellent, especially the live chat feature.
Plus as a bonus, compared to other companies, their website (including the client area cPanel) actually looks good.
I highly recommend choosing Relentless Hosting!
