Two days ago, I upgraded to the 100mbps tier. Doing speedtests now at https://nbnspeedtest.telstra.com/, im getting only around 10mbps. I am using a desktop PC which has a TP-LINK TL-WPA4220KIT powerline adaptor extending the wifi to my room, which I then use an ethernet cable to my PC. I'd been getting around 36mbps before that. On mobile devices, using both the 2.4g and 5g its still getting under 10mbps, with high pings from the tests.
Is telstras services just slow at the moment or is something going on?

This is what it says from navigating there. My PC, which is using ethernet is now gone back to its usual 36mbps, but mobile devices still slow. On the 5g its at under 10mbps, on the 2.4g getting 25mbps.
I purchased the premium speed boost, which looking at my bigpond account, says its active, this was two days ago, supposed to be at 100mbps tier.
From those stats it looks like your link is only capable of 42.5 Mbps down and 11.5 Mbps up so it is not worth paying for the 100/40. You will get same speed on the 50/20 tier. The maximum speed an NBN link is capable of is dependent on distance from Node. It is also dependent on the quality of the street cable and internal house wiring. If you have more than one phone socket make sure nothing is plugged into the other sockets. If using ADSL Filter splitter remove it and connect gateway DSL port directly to phone socket.
If there are several walls between Gateway and mobile devices or Mobile devices over 15 Meters from gateway then speed on 2.5 GHz band will be faster than 5 GHz band. There could be interference from neighbouring networks on the 2.4 GHz band which will result in lower speeds. You could try changing the channel on the 2,4 GHz band. There are free WiFi analyzer apps that you could install on your mobile that will show which channel suffers the least interference.
Thanks for the information.
In regards to only having a max of 42.5Mbps download. Is that because I'm still using the default Telstra modem I was given with my NBN? If I purchased a new higher tier modem could I potentially get faster speeds?
Funnily enough you may actually lose a few mbps on a more expensive modem. When it comes to sync speed as far as the modem is concerned (taking out distance to the node and all other factors), that's controlled by the DSL chip in the modem. The DSL chip in the Sagemcom modem (BCM63168) generally sync's at a slightly higher download rate at the expense of stability and a few other features compared to the BCM63138 Chip in more expensive models
