As of October 2026, the 3 highest-ranked environmental consultants in Perth, WA on the Starworks directory are E-Precision Laboratory Pty Ltd (5.0 stars from 10 Google reviews), Western Geotechnical & Laboratory Services (5.0 stars from 8 Google reviews) and Opira WA (5.0 stars from 7 Google reviews).

How many environmental consultants does Starworks rank in Perth?
Starworks ranks 61 environmental consultants in Perth, WA, holding 209 Google reviews between them. Across the 61 the median rating is 5.0 stars from a median of 2 reviews. Of the 61, 52 are rated 4.5 or better. The most-reviewed carries 11 reviews, more than the top-ranked environmental consultant holds, which is why rating alone does not set the order.
What star rating should I expect from a good environmental consultant in Perth?
The median Google rating across the 61 environmental consultants Starworks ranks in Perth, WA is 5.0 stars, and 52 of them sit at 4.5 or above. A rating at or near that median is ordinary for environmental consultants in Perth, WA rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.
How many Google reviews does an established environmental consultant in Perth have?
The median environmental consultant Starworks ranks in Perth, WA carries 2 Google reviews. The most-reviewed of them carries 11.
How does Starworks rank environmental consultants in Perth?
Starworks gives every environmental consultant in Perth, WA a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it by website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0 and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well, and every listing links to them on Google.
Why does a environmental consultant in Perth with all 5-star reviews score lower than one with a lower rating?
Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer environmental consultant with a handful of excellent reviews may still be the right choice in Perth, WA. The star rating and review count sit next to every score so you can weigh both yourself.
Why does the same environmental consultant not appear several times on this list?
Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so Starworks groups them and shows the business once, using the listing with the strongest review record. That is why this page opens with 50 distinct environmental consultants in Perth, WA rather than a longer list of repeats.
How often is this list of environmental consultants in Perth updated?
This ranking of environmental consultants in Perth, WA rebuilds on a 30-day cycle and prints the date of its last rebuild above the list, which for the current version is October 2026. Ratings and review counts are re-read from Google over time rather than on a fixed schedule, so an individual figure here can be older than the rebuild date.
How can I improve my environmental consultant business ranking in Perth?
Collect genuine customer reviews consistently, and keep a working website and phone number on your Google listing, because those are the three inputs the score reads. There is no placement to buy on this page. For scale: the median environmental consultant Starworks ranks in Perth, WA carries 2 Google reviews at 5.0 stars.
