Irrigation System Prices

An irrigation system in Australia costs $800–$1,800 for a small pop-up sprinkler install, $2,500–$6,500 for a full-property reticulation system, $600–$2,000 for drip irrigation, and $400–$1,200 for a smart controller upgrade. Prices include GST.

Reticulation installation in Perth costs $2,450–$6,370 for a full-property system. Small garden pop-up systems cost $780–$1,760. Perth has a highly competitive reticulation market and many properties already have bore access, which reduces ongoing water costs. Two-day watering rosters apply.

Drip irrigation installs cost $600–$2,000 compared to $800–$3,500 for pop-up sprinkler systems. Drip is generally cheaper to install for garden beds but requires more components (emitters, pressure regulators, filters) per metre. Long-term running costs are lower as drip delivers water directly to plant roots with minimal evaporation.

A smart irrigation controller is a WiFi-enabled timer that adjusts watering schedules based on real-time weather data, soil moisture, and seasonal conditions. Installation costs $400–$1,200 in Australia. Smart controllers typically reduce water use by 30–50% compared to fixed timers, paying for themselves within 1–2 seasons in areas with water charges.

Requirements vary by state. In Western Australia and Queensland, irrigation contractors must be licensed. In other states, any work involving connections to the mains water supply must be done by a licensed plumber. Always check your state or territory requirements before engaging a contractor.

In Australia, "reticulation" typically refers to an automatic in-ground sprinkler system for lawn and garden watering, and the term is used most commonly in Western Australia. "Irrigation" is the broader term used across all other states and countries, covering all methods of delivering water to plants including sprinklers, drip systems, soaker hoses, and flood irrigation.

A small pop-up system for a single garden zone typically takes 4–6 hours. A full-property reticulation system covering lawn and garden areas usually takes 1–2 days. Complex installations with bore connections, many zones, or difficult excavation conditions can take 2–3 days.

A standard irrigation quote should include: design and zone layout, supply of all pipes (poly pipe), fittings, solenoid valves, heads, controller, and rain sensor; trenching and installation; backfill and reinstatement; and commissioning and programming. Confirm what is excluded — bore pump installation, concrete cutting, council approvals, and fencing reinstatement are often charged separately.

Bore pump installation in Australia costs $1,800–$5,000 for a standard residential submersible or surface pump connected to an irrigation system. Cost depends on bore depth, pump capacity required, and access. Bore water eliminates mains water costs for irrigation, typically recovering the pump cost within 2–5 years.

Yes — for most Australian homes with a lawn or garden, a well-designed irrigation system delivers significant labour savings, better plant health from consistent watering, and reduced water waste compared to hand watering or hose use. In states with bore water access, ongoing water costs approach zero after the pump is installed.

Annual servicing is recommended for most residential irrigation systems. A service typically includes: checking all heads for correct operation and coverage, adjusting head alignment, replacing worn heads, flushing filters, testing solenoid valves, reviewing controller programming, and checking for leaks. Service costs $120–$350 depending on system size.

The biggest cost factors are garden size and number of zones, the type of irrigation system (pop-up vs drip vs soaker), whether a bore pump is required, soil conditions affecting excavation difficulty, and the controller type. Competing quotes from 2–3 licensed irrigators is the best way to get accurate pricing for your specific garden.
