The Be Connected Learning Platform is sponsored by the Federal Government Department of eSafety and can be found at https://beconnected.esafety.gov.au/
On this site you can find free online courses and resources designed for seniors but can be used by anyone to learn about various topics associated with the use of phones, tablets and computers.
If you want to keep track of your progress, you can sign-up (i.e. create yourself an account). If you just want to check out what is available, you can just browse the topics and do the tutorials on those of interest to you.
Be Connected also provides, resources, including grants from the Australian Government. to organisations (Network Partners) across the country who run free digital mentoring services for seniors. Living Connected has been a Network Partner since the program started in 2017. If you are a learner, make sure you don't go to the Be Connected Network Partner website which is different from the learning platform.
