How much does Google Ads cost in Australia?
Google Ads cost in Australia varies widely by industry, location and competition. On average, Australian small-to-medium businesses spend between $1,500 and $5,000 per month on ad spend, with average cost per click (CPC) ranging from $2 to $25. Service-based industries like legal, medical and trades sit at the higher end, while retail, hospitality and lifestyle brands tend to pay less per click.
Average CPC in Brisbane and Gold Coast
Brisbane sits close to the national average for paid search. Tradies and home services typically pay $8–$15 per click, dental and medical clinics $6–$12, real estate $3–$8, and law firms can pay $10–$25 per click for high-intent terms like "personal injury lawyer Brisbane".
Gold Coast generally runs about 10% cheaper than Brisbane for the same industries due to slightly lower competition density. National "Australia-wide" campaigns tend to be 10–15% more expensive than metro-only Brisbane campaigns because you're competing against bidders from Sydney and Melbourne.
How to reduce your cost per lead
Cost per lead (CPL) is the metric that actually matters — not CPC. You can lower CPL without lowering your bids by improving the conversion rate of the people clicking your ads. The biggest levers are:
- Dedicated landing pages — sending ads to your homepage typically halves your conversion rate. A focused landing page with one clear call to action can lift conversions from 4% to 10%+.
- Negative keywords — adding "free", "DIY", "jobs" and other irrelevant terms stops Google wasting your budget on non-buyers.
- Conversion tracking — without proper call and form tracking, Google's algorithm has no idea which clicks are actually becoming leads, so it can't optimise.
- Geographic targeting — tightening your radius to only the suburbs you actually service can dramatically improve lead quality.
- Ad copy that pre-qualifies — mentioning price ranges, service areas and minimum job sizes filters out tyre-kickers before they click.
Why most Australian businesses overpay for Google Ads
The most common reason businesses overpay is they hand the account to a generalist agency or freelancer who never installs proper conversion tracking. Without that, every optimisation decision is a guess. The second most common reason is running Performance Max or "Smart" campaigns on autopilot — these can work, but only when paired with clean data, strong creative and a tight feed.
Use the calculator above as a baseline, then compare it against your actual numbers. If your cost per lead is more than 50% above the estimate for your industry, there is almost certainly a fixable problem in your account.
