To pick the best among all other nbn providers, you need to first access your needs. It is your needs that will determine the provider and the nbn plans you choose. Different providers offer different plans and as such, a single provider will not suit the needs of everyone.
A look at the nbn bundle plans offered by a provider will tell you whether the provider is right for you. If you only need internet for emailing, browsing the internet and for entertainment on social sites, a provider offering moderate speed nbn internet plans and allowing upload-download will do just fine. If you do not need a big download quota or a high speed link, then there is no need paying for them.
If you have a large family with each member using the internet, you stream music, movies and TV and you play online games, you will need faster internet. Compare different plans to see which will offer you the best. You might even go for nbn unlimited data.
Estimate the amount of data in gigabytes you need for downloads and uploads. When doing so, be aware that you may need more data with nbn than you would with ADSL. In Australia, most people will be tempted to download higher quality content when the internet connection is fast.
Because it is not easy working out a download quota, most Australians go for nbn no contract plans. These no contract internet plans allow you to ditch a poor provider whenever you feel you are not getting value for your money. As long as you have the nbn router or nbn connection, you can pick a provider of your choice.
