As of October 2026, the guide has 21 diagnostic services across 11 suburbs, most of them in East Toowoomba, Pittsworth and Rangeville. Of those, six have a website we check every day. The other 15 come from public records, with a phone number where one is published.
As of October 2026 the Toowoomba Business Guide lists 21 diagnostic services across 11 suburbs, from the city centre to Highfields, Oakey and the Downs towns.
East Toowoomba, Pittsworth and Rangeville have the most listed diagnostic services. Every suburb with at least one is on this page.
Every day the guide checks each business it lists. A business comes off the guide only when there is clear sign it has closed, seen on two checks at least 7 days apart. A slow or briefly down website never removes it. Of the 21, 6 have a website that is checked daily.
Listing is free and takes about two minutes at https://toowoombabusinessguide.com.au/add/ with no account. If your business is already here, open its page and click This is my business to claim it; claimed listings appear first in search.
