Most web builder platforms will provide free basic hosting. However, this will normally be very limited in size and your domain will include the platform’s name. This will impact the trust in your website as well as what you can do with your site.
The best web hosting Australia has to offer will be from around a couple of dollars a day, meeting not only your website requirements, but also that of user experience and Google too. Most web hosts will have varying packages, so be sure to speak to someone who can guide you on what you need, if you’re not sure.
