If you are tech savvy, you might not need much handholding. In such a case, you only need a shared web host that offers round-the-clock support to help you navigate simple configurations. When you do not know how to do any configurations, and you know nothing about SSL certificates or web security, choose managed/dedicated hosting.
You need to estimate the amount of traffic you expect before you pick a host. Most web hosting Australia services charge based on bandwidth usage. Bandwidth refers to the bytes you serve in a given period. If yours is a simple site with only a few visitors, your bandwidth will be low. If, however, your site ranks on the first page of Google\'s search engine results, you will need more bandwidth.
You need to understand servers. The cheapest hosting option is a shared server where a single box serves different websites. Here, you are restricted and your website may be slow. There is also VPS, Virtual Private Server, where a virtual machine runs on the server. VPS offers faster load speeds. The best is dedicated hosting where you get a private server.
Lastly, check out for the best offers but be wary of unrestricted bandwidth and storage offers. Some deals are not what they are purported to be, especially if you the web host has unlimited offers for a few dollars every month. You should also own your domain name in case you need to change hosts.
