Ten telephone and Internet service providers accounted for 93.4% of the complaints.
Optus, the second largest telco in the country, kept its position in the complaints queue as well, with 40,665 complaints against it, a year-on-year rise of 35%.
However, a good number of others saw the number of complaints fall on a year-by-year comparison:
- Vodafone received 9752 complaints, a year-on-year decrease of 8.7%;
- iiNet received 7719 complaints, a year-on-year decrease of 24.1%;
- TPG received 6248 complaints, a year-on-year decrease of 10.7%;
- Dodo received 3120 complaints, a year-on-year decrease of 5.7%;
- M2 Commander received 1565 complaints, a year-on-year decrease of 8.2;
- Southern Phone received 1484 complaints, a year-on-year decrease of 28.2 per cent.
But small ISP MyRepublic saw a year-on-year increase of 101.6%, fielding 1816 complaints.
MyRepublic contested this rise, with its managing director Nicholas Demos saying: "MyRepublic is a relative newcomer, only launching in late 2016, which is why it did not register full data for the previous year.
"Therefore, while the figure for the total number of complaints in the most recent financial year is correct, it is impossible to calculate a year-on-year shift without having been in full operation for the previous year."
