Karratha WA Investment Brief

Karratha, WA — Suburb Investment Analysis

## 1. Investment Verdict HOLD. The single most important number is 5.4% gross rental yield — this is the only reason to stay in this market. The 5-year CAGR of -1.6% per year tells you capital growth has been negative over the medium term despite a strong 16.5% bounce in the past year. You are not buying for long-term wealth here.

## 2. Market Overview The median house price sits at $601,401, with units at $545,196. The 1-year price growth of 16.5% looks strong on the surface, but the 5-year CAGR of -1.6% per year reveals this is a volatile, boom-bust market. The 3-year growth forecast of 13.5% suggests modest recovery, not a sustained rally.

Days on market data is not available, but the market cycle is rated stable, not hot. This signals a balanced market — neither strong buyers' nor sellers' market. If you are an existing owner, hold. If you are a new buyer, you are not getting a bargain.

## 3. Rental Market Vacancy rate sits at 3.0% — right on the edge of balanced (under 3% is tight). Rental demand is rated moderate, not strong. The median weekly rent of $620 generates a gross yield of 5.4%, which is decent for a regional market but not exceptional compared to other WA regional towns like Dongara (5.2%) or Esperance (3.5%).

The owner-occupier rate is just 32% — this is a renter-dominated market. That means tenant turnover risk is higher, and you rely heavily on the local employment base to keep tenants in place. With unemployment at 2.7%, jobs are plentiful today, but that is tied to one industry.

## 4. Short-Term Rental Opportunity The STR numbers are weak. Median nightly rate is $385, but occupancy is only 15%. That means the property sits empty 85% of the year. Estimated annual revenue at that occupancy is roughly $21,000 (385 x 0.15 x 365). Compare that to long-term rental income of $32,240 per year (620 x 52). LTR outperforms STR by over $11,000 annually. Do not use STR here.

## 5. Infrastructure & Growth Drivers There are no major projects on file for Karratha. Transport is standard suburban access — nothing special. The primary economic driver is the resources sector (mining and energy). With unemployment at 2.7%, the local economy is running hot, but that is entirely dependent on commodity prices and mining company decisions.

There is no diversification. No major government infrastructure spending. No population growth driver beyond fly-in-fly-out workers. The population is just 98 people — this is not a growing residential hub. It is a service town for resource operations.

## 6. Bull Case If commodity prices stay strong and mining companies maintain or expand operations, Karratha could see continued rental demand. The 3-year growth forecast of 13.5% would take the median house price to roughly $682,000. Combined with the 5.4% yield, total return over three years could be around 18.9% (13.5% capital growth + 5.4% annual rental income). That is a reasonable outcome if conditions hold.

The supply pipeline is low — price growth is outpacing new supply. Limited new construction means existing stock gains pricing power if demand holds.

## 7. Risks Single-employer dependency: The local economy is tied to mining. If commodity prices drop or a major operator reduces headcount, vacancy rates spike. The 3.0% vacancy rate today could easily double to 6% in a downturn.

5-year CAGR of -1.6% per year proves this market does not build long-term wealth. You are relying on timing the cycle correctly.

Distance from CBD is flagged as a risk in the scorecard — this is valid for Karratha as it is over 1,500 km from Perth. That limits the buyer pool to local workers only. No tree-change or lifestyle buyers are coming here.

Population of 98 means the tenant pool is tiny. One major employer leaving could empty the town.

Rate sensitivity: With 68% of properties being rentals (100% minus 32% owner-occupier), any interest rate rise that pushes investors to sell could flood the market with supply.

## 8. The Play Entry range: Do not buy at current prices. If you already own, hold for yield. If you must buy, target a minimum 6.0% gross yield to compensate for the capital growth risk. That means negotiating below $601,000 median.

Watch signals: Monitor iron ore and LNG prices monthly. Track vacancy rate — if it moves above 3.5%, exit. Watch for any major mining company announcement about workforce reductions.

Recommended strategy: Hold existing properties for cash flow. Do not add to position. If you are an existing owner, use the current strong rental market to lock in long-term tenants at $620/week. Do not chase capital growth here — it has not delivered over 5 years.
