Next time if you are conducting business travel in Australia, I would recommend Astra Apartments (serviced apartment between Sydney and Melbourne) and Fat Free Fone Company (mobile broadband internet) services.
Astra Apartment (Chatswood)
During my recent stint back in Australia, I stayed in their Chatswood apartment. The location was close to Microsoft office (North Ryde/ Macquarie Park) area and conveniently located among the Chatswood shops. The apartment was generally well maintained and decorated in a sensible and modern fashion. Their charges were reasonable (compared to long term hotel rates) and staff member was generally responsive and helpful.
Fat Free Fone Company offers fixed line, mobile phone and mobile broadband rental services in Australia.
I needed Internet access after office hours and during inter-state trips and found their services fairly reliable. It cost 200 AUD p/ month for 4GB of data (caveat: upstream and downstream usage INCLUSIVE) per month. It works out just under $7 p/day, much cheaper compared to hotel internet charges, accompanied with the flexibility of a short term nationwide mobile broadband rental.
I am not in any commercial arrangement with the above mentioned companies. These are my personal comments and should not be transmitted beyond my blog.
