Welcome to the community!
I used your community details to pull up the account and I got a match. I ran initial tests on your connection and it shows connected for 1d 1h 26m and getting a passing speed on the line.
Getting download of 4.8 Mbps and upload speed of 0.8 Mbps is passing based on your location's distance to the exchange which is 3607m is passing. You can check it here.
If you are often steaming movies online and play online games at the same time, you may experience bandwidth sharing issue considering the speed you're getting from the line.
I suggest upgrading your service with NBN service, however it is not yet available in your area. You can visit this link for reference.
