Chombo have dropped there prices on hosting plans:
$3.95= 1GB space 50GB transfer
$6.95= 2GB space 75GB transfer
$9.95= 3GB space 100GB transfer
All plans include 8.30- 5.30pm phone support.
This is cheap as for Australian Hosting!!
Also they have .com.au domains for $20.95 for 2 years (cheapest you will find)
Their company info shows they're registered in South Australia. Lookup of the parent company "Sonet pty ltd" shows they're in QLD, updated their details there as of just June last year, so I doubt they've moved. The registration for Sonet's domain (and also Chombo) is "Curtis Bayne" who registered it at an @neural.com.au email - also in QLD. Apparently he's just a rep of Chombo according to his Whirlpool page, given he registered all the domains you'd have to assume he's the owner, as it's not a big company according to Neural's about page. Looked up Chombos twitter page, "Brisbane-based Australian web host".
Contact page says they have an office in Melbourne at 101 Collins St, yet the buildings website which lists tenants show none of those names.
So they're registered (and have their current address listed at) South Australia, yet they apparently are in an office building in the middle of Melbourne, but are apparently also in Brisbane…
Doesn't sound like a good offer IMO, they can't even be transparent about their location.
EDIT:
Turns out they've recently sold, not sure who the new owners are (or their 'address' lol): http://blog.chombo.com.au/?p=41
