She is a long-range frigate capable of air defence, surface and undersea warfare, surveillance, reconnaissance and interdiction. Toowoomba's combat capabilities have been significantly improved under the Anti-Ship Missile Defence upgrade program, a world class program that provides an enhanced sensor and weapons systems capability
She is a 3,600-tonne (3,500-long-ton) ship, 118 m (387 ft) in overall length, 4.8 m (49 ft) across the beam and had a draught of 4.35 m (14.3 ft) at full load. She is capable of a 27-knot (50 km/h; 31 mph) top speed, and a range of 6,000 nautical miles (11,000 km; 6,900 mi) at 18 knots (33 km/h; 21 mph). Her hull and superstructure are of all-steel construction, and the ships are fitted with fin stabilizers.

On 18 January 2010, Perth docked at the Australian Marine Complex in Henderson, Western Australia to be modified under the Anti-Ship Missile Defence Project. The upgrade, intended to improve the class' anti-ship self-defence capability, included the fitting of CEA Technologies' CEAFAR and CEAMOUNT phased array radars, a Vampir NG Infrared Search and Track system, and Sharpeye Navigational Radar Systems, along with improvements to the operations room equipment and layout. Both of the frigate's masts were replaced; the top of the aft mast now sits at 38.7 metres (127 ft), making Perth the second-tallest ship in the RAN.
Because of the added equipment, additional ballast was added to improve the frigate's stability, and the ship's quarterdeck was enclosed. The additional weight brought the ship's full load displacement to 3,810 tons.
After the upgrade was completed in October 2010, Perth was used to trial the modifications before they were rolled out to the rest of the Australian Anzacs: alongside and harbour trials at HMAS Stirling were successfully completed in February 2011, and full sea trials began on 21 February.
On 27 April, the frigate sailed to the east coast of Australia to continue trials, with further testing to occur at the United States Navy's Pacific Missile Range Facility, then during Exercise Talisman Sabre. Testing was completed by July 2011, and the rollout of the ASMD upgrade across the class was approved in November 2011.
In October 2013, Perth participated in the International Fleet Review 2013 in Sydney.
During February and March 2015, an MH-60R Seahawk Romeo helicopter from 725 Squadron RAN was embarked aboard Perth for at-sea trials of the new helicopter.
