Cost (AUD) $150–$800

A new dishwasher is one of the most common kitchen plumbing jobs in Australia. The unit itself runs $600 to $3,000 retail. The install is licensed plumber work and adds $150 to $800 to the bill depending on whether connections already exist.

Install cost breakdown

ScenarioPlumber cost (AUD)
Like-for-like swap (existing connections all there)$150 to $280
First-time install, existing power point + drain$250 to $450

Plus the dishwasher: $600 to $1,200 for budget, $1,200 to $2,500 for mid-range, $2,500 to $4,500 for premium (Bosch, Miele).

What the plumber does

  1. Disconnects the existing unit if applicable
  2. Confirms the under-sink stop valve is sound and isolates
  3. Fits a new dual-isolation valve (so future replacement is easier)
  4. Connects the flexible water supply hose to the dishwasher inlet
  5. Connects the waste hose to the kitchen sink waste fitting (or directly to a P-trap)
  6. Plugs into the under-sink power point (no electrical work needed if a point exists)
  7. Levels the unit using its adjustable feet
  8. Fits the anti-tip strap to the underside of the bench
  9. Runs a test cycle to check for leaks
  10. Provides a Compliance Certificate where the state requires one

Most of this can be done in 90 minutes. Add 30 to 60 minutes for first-time installs.

Why DIY is not the move

In every Australian state, connecting a dishwasher’s water supply is plumbing work. The drain connection in most states is also licensed work. The risk if you DIY:

  • A failed water connection floods the kitchen overnight
  • Your home insurance refuses to cover the damage because unlicensed work caused it
  • Manufacturer warranty on the dishwasher void
  • You’re liable for any damage to flats below

The $200 you save is not worth a $30,000 water damage claim.

Choosing a dishwasher

The Aussie dishwasher market has three quality tiers:

  • Budget ($600 to $1,200): Westinghouse, Dishlex, Whirlpool, basic Bosch. 8 to 9 years lifespan typically.
  • Mid-range ($1,200 to $2,500): mid-range Bosch, Beko, Asko, Fisher and Paykel. 10 to 12 years.
  • Premium ($2,500 to $4,500): high-end Bosch (Series 8), Miele, Asko top range. 15 to 20 years.

Things that matter more than price:

  • Water and energy rating (3-star min for water, 4-star+ for energy)
  • Noise level (dB rating, under 44 dB for quiet, under 40 dB for premium quiet)
  • Number of place settings (12 to 14 standard for family)
  • Cycle options (eco, intensive, half-load, sanitise)
  • Cutlery tray vs basket (tray loads better)

Hiring a plumber

The job is small enough that most plumbers won’t quote sight-unseen. Get them to inspect:

  • Existing under-sink stop valve condition
  • Existing drain configuration (basket waste, P-trap)
  • Power point location
  • Cabinet space (some integrated dishwashers need precise widths)

Two quotes is usually enough for a job this size. Verify licence number on the state regulator’s register before booking.

Frequently asked questions

How much does it cost to install a dishwasher in Australia?

$150 to $350 for a straight swap where existing connections (water, drain, electrical) are already there. $400 to $800 for a first-time install where new connections must be added. Add the dishwasher itself ($600 to $3,000).

Can I install a dishwasher myself?

No. Connecting a dishwasher to the water supply is plumbing work; in some states the drain connection also requires a licensed plumber. The electrical connection to a 10A power point is fine if a point exists, but adding a new power point is licensed electrical work.

What's involved in a dishwasher install?

Connecting cold water from the under-sink stop valve via a flexible hose, connecting the drain to the kitchen sink waste, plugging into an existing power point, levelling the unit, anti-tip strap into the cabinet.

Do I need a new power point for a dishwasher?

Usually no, you can use the existing under-sink GPO if you have one. If not, you need a sparky to add one ($150 to $300).
