This is a broad modelled estimate, not a verified market range. It starts with the sourced indicative new price of $98,000 and applies HeavyBook’s declared depreciation curve for excavators at the reference ages shown above. A real machine can sit outside it because of hours, condition, attachments and location. See the method →

The five-tonne class is one of the busiest segments of the Australian mini-excavator market, and the current-generation 305 CR is Cat's entry in it — a compact-radius machine whose tail stays close to the tracks for work on tight urban and residential sites. Plumbers, landscapers and small civil contractors buy it, and hire fleets stock it heavily. Australian machines typically carry a hydraulic quick coupler and a bucket set, in canopy or sealed cab. The long-stick and counterweight options change dig depth, weight and lift capacity meaningfully, so confirm the exact configuration of a used unit. Cat's launch pitch here was stronger breakout and deeper standard dig than the outgoing model it replaced — the practical difference buyers notice on the tools.

What a Cat 305 CR is used for

The Cat 305 CR is a five-tonne compact-radius midi excavator — the size that covers most residential and light civil digging while still floating on a standard plant trailer.

  • Residential footings and site cuts
  • Drainage and service trenching
  • Landscaping and retaining-wall excavation
  • Tight-site work against fences and walls

What Moves the Price

Adds the most

Hitch + bucket set

A hydraulic hitch with a proper bucket set is the single biggest add. Machines sold bare consistently land at the low end of the range.

Clear premium

Low hours for age

Well under average annual hours reads as a weekend machine. Buyers pay a visible premium over the same year at contractor hours.

The floor

Auction vs dealer

Auction is the floor of the market. Dealer and private sales recover most of the gap — at the cost of time and effort.

Priced off the top

Tracks & condition

Worn rubber tracks and tired pins get quoted straight off the asking price — buyers price the fix before they price the machine.

305 CR Price FAQ

How much is a used Cat 305 CR worth in Australia?
HeavyBook's indicative used-price estimate spans $22,000–$71,000, with $42,000 as the 8-year mid-life reference. The low and high points use 14-year and 3-year reference ages. This is modelled from a sourced new price and a declared category depreciation curve — not verified sold data. Age, hours, condition, attachments and location can move a real machine outside the band.
Is this estimate based on real sold prices?
No. It is a transparent modelled reference while verified sold-price data is unavailable. HeavyBook keeps it visually separate from market ranges, publishes the assumptions, and never uses it as an offer, valuation or sample-sized market figure.
What is a Cat 305 CR used for?
The Cat 305 CR is a five-tonne compact-radius midi excavator — the size that covers most residential and light civil digging while still floating on a standard plant trailer.
How much does a Cat 305 CR weigh?

What engine is in a Cat 305 CR?

How deep can a Cat 305 CR dig?
The Cat 305 CR has a maximum dig depth of 3.42 m (standard stick); 3.67 m (long stick).
How much is a new Cat 305 CR?
A new Cat 305 CR is around $98,000 ex-GST (Indicative new price for the current Cat 305 CR (5t, standard config), ex-GST. Cat is quote-only; this is an equipment-finance indicative 'new from' figure.). Used examples list for less; HeavyBook's equipment finance calculator estimates the monthly repayment on either.
What makes one 305 CR worth more than another?
Hours for age matter most, then attachments — a hydraulic hitch with a proper bucket set lifts the price, and machines sold bare sit at the low end. Track condition, service history and where it sells (dealer, private or auction) move the rest.

Buying a Cat 305 CR

Check it is not encumbered

A search shows whether someone else has registered a security interest over the machine — a financier who can repossess it after you have paid the seller — and whether it has been reported stolen or written off. It does not tell you what is owed, and it is not a valuation.

Tracked excavators sit right on the boundary of the motor-vehicle test, so do not rely on a serial search alone. Run both searches — by serial or chassis number, and against the seller.

Search the Personal Property Securities Register. The register publishes a case study on buying heavy construction equipment privately.
