On Wednesday, 24th September 2025, I activated The Knoll Conservation Park VKFF-0937, using the special event call of VI8POL.
The Knoll is located at Crafers West, about 12 km southeast of the city of Adelaide.

My main objective for the day was to operate near the Police Heritage site at Crafers West. It was a bonus that the park was located virtually alongside the memorial, so I decided to activate the park for the World Wide Flora Fauna (WWFF) program.
The Knoll Conservation Park is about 2 hectares (4.9 acres) in size. It is located on the corner of Waverley Ridge Road, Sheaok Road, and Upper Sturt Road.






The park was formerly known as The Knoll National Park Reserve and The Knoll National Pleasure Resort. It commenced as a National Pleasure Resort in 1917. On the 9th day of November 1967, it was proclaimed as The Knoll National Parks Reserve. On the 27th day of April 1972, it was reconstituted as The Knoll Conservation Park.

In an October 1911 issue of The Register newspaper, the following was reported about The Knoll:
“The Knoll is a beautifully situated block of land – on the very top of the Waverly Ridge – about 2,100 ft above sea level, situated right alongside a perfect road, easily accessible from Adelaide and the main roads. It commands one of the finest views in the State to all points of the compass.”

The Police Heritage site is located just to the north of the park on Waverly Ridge Road. Sergeant Cecil William Sparkes, 46, Special Constable Mervyn George Casey, 23 and Special Constable Colin Roy Kroemer, 33, lost their lives while fighting a bushfire in the vicinity of Fosters Gully in January 1951.


On the evening of Thursday, the 18th day of January 1951, a fire commenced at Brownhill Creek. It crossed part of the Belair National Park and travelled towards Crafers on Friday, the 19th day of January. It was reported that by 11.00 a.m., ‘the situation was alarming and calls for help were broadcast.’ (Trove 2025)
By midday, the fire was centred in Fosters Gully, Upper Sturt Estate. Stirling Fire Controlling Officer Mr Stan Hampton and Mr Harry Norris, a team of 20 men, went to the bottom of a gully with knapsack sprays. The men split into two groups, and shortly afterwards, the wind changed, and this caused the smoke and flames to isolate the group of men led by Norris. This included Sparkes, Casey, and Kroemer. (Trove 2025)
In The Advertiser, Saturday 20th January 1951, Norris stated:
“They were trapped in a pall of fire and smoke….the only thing those with me could do was to run through the flames.‘ (Trove 2025)
Three other police officers and several civilians were treated at the Stirling Hospital. The injured police officers were Sergeant Instructor Geoffrey Hearnes, Special Constable Thomas John Sears, and Special Constable Neil Lionel Wauchope.

On Friday, the 26th day of January 195, the SA Police Association launched an appeal for the dependants of the three deceased police officers. It was known as The Police Bushfire Appeal. The Commissioner of Police, Mr Ivor Green, the State Secretary of the RSL, Mr F.U. Hall, and the Mayor of Glenelg, Mr. C.H. Fidock were appointed as trustees to the fund. The Governor, His Excellency Sir Willoughby Norrie, and Lady Norrie, were among the first to donate to the appeal. (Trove 2025)

An inquest into the deaths commenced on Friday, the 16th day of February 1951. It was conducted by the City Coroner, Mr T. E. Cleland.

During the inquest, it was revealed that Sparkes, Casey, and Kroemer, were ‘engulfed in flames’. The investigation conducted by Detective A.R. Calvesbert and the inquest failed to ascertain who was responsible for the lighting of the fire. It was believed that the fire was not intentional, but was likely lit through carelessness.

My operating spot was on the walking trail leading up to the communications equipment. I ran the Yaesu FT857, 40 watts, and the 20/40/80m linked dipole supported by a 7 metre telescopic squid pole.
When I first set up, the 40m band was very quiet with no noise, despite me being surrounded by houses. However, on my second round on 40m, the noise floor had increased to strength five. I also had to endure the noise of the traffic on the busy Waverly Ridge Road and someone operating a chainsaw on a property near the park. Despite this, it was a good activation and a great way to honour the 3 police officers who lost their lives.
