So I had Telstra Tech come the other day and found no issues with the lines as thought previously. I then had another TPG tech come and inspect and test again, he found that it was an issue with my modem/router (only 10 months old). I checked and it had auto updated firmware to the newest version which now has issues and slows my download speeds. I have replaced my Netgear D7000 with a new one and now speeds are back to normal. Thanks to all involved.
