Rocky Point Mill is a raw sugar factory located at Woongoolba, on the boundary with Steiglitz, in the northern City of Gold Coast, Queensland. It is the southernmost operating sugar mill in Queensland and is owned by W.H. Heck & Sons Pty Ltd, remaining under the control of the Heck family more than a century after its establishment.

Rocky Point is unusual among Queensland sugar mills in relying entirely on road transport for delivery of harvested cane. The mill formerly operated its own 610 mm (2 ft) gauge cane tramway, but this closed in 1951.

History

Establishment

Rocky Point Mill was established by German immigrant Carl Heinrich Heck. Heck arrived in Queensland in 1866 and settled near Alberton, where he operated a grist mill and began growing sugar cane. His cane was initially sent to Rehfeldt's mill at Alberton for crushing.

In 1878, Heck moved to Rocky Point, near the mouth of the Logan River, where he established a small farm and began constructing his own sugar-processing operation. The first Rocky Point mill was operating by 1879. It was a small family-run factory with hand-fed rollers and open-pan sugar production.

Some modern sources give 1878 as the establishment date, reflecting the year Heck moved to Rocky Point and began developing the property. The mill itself traditionally marked its establishment from 1879, including celebrating its centenary in April 1979.

In 1886, Heck purchased a vacuum pan from William Gibson's Clydesdale Mill at Hemmant, whose owners had relocated to Bingera near Bundaberg. The acquisition began a long tradition of purchasing and reusing machinery from other sugar mills.

Expansion

During the late nineteenth century the Logan and Beenleigh districts contained numerous small sugar mills. In 1885 there were approximately 40 mills in the Logan district, but this had fallen to 18 by 1888 and nine by 1900.

Management of Rocky Point passed to Carl Heck's son Wilhelm Heinrich Heck during the early twentieth century.

A major expansion followed the closure of the government-owned Nerang Central Mill at Benowa in 1917. W.H. Heck purchased the Nerang machinery for £5,000 and progressively installed it at Rocky Point. The improvements increased the mill's crushing capacity substantially.

The Junction Mill near Norwell closed in 1919 and Rocky Point subsequently absorbed much of its cane supply. In 1921 Rocky Point crushed 5,162 tons of cane; by 1924 this had increased to 16,238 tons.

Four other sugar mills were still operating in the Logan district in 1924, at Steiglitz, Alberton, Carbrook and Eagleby. These progressively closed, with the final competing mill ceasing operations in 1943, leaving Rocky Point as the sole surviving mill in the district.

W.H. Heck & Sons Pty Ltd was established in 1932 to operate the family business. Successive generations of the Heck family have continued to own and manage the mill.

Tramway

Construction

Increasing cane production around Norwell led growers to request a tramway connection to Rocky Point during the early 1920s. An Order authorising construction was approved by the Governor-in-Council in March 1923.

Construction was carried out during 1923 under the supervision of the Beenleigh Shire engineer, with local farmers providing much of the labour. The 610 mm (2 ft) gauge line followed road reserves across the low-lying country between Woongoolba and Norwell.

The tramway was officially opened on 16 August 1924 by J.G. Appel MLA. It consisted of a main line towards Norwell together with a branch serving farms around Norwell Bridge.

The railway was particularly vulnerable to flooding because much of the route crossed low-lying swamp and salt-marsh country. Flood damage and the resulting deterioration of the lightly constructed track became an increasing maintenance problem.

Closure

Improved roads and the increasing availability of motor trucks after the Second World War reduced the advantages of rail transport. Rocky Point closed its tramway in 1951 and thereafter relied on road transport for delivery of cane.

Most of the railway was subsequently lifted, although internal rail tracks remained within the mill yard for cane-bin handling.

Preserved locomotive

The Rocky Point tramway was operated by a small John Fowler & Co. 0-4-0WT steam locomotive, works number 16249 of 1923. The locomotive was ordered specifically for the new tramway and worked cane trains between the mill and Norwell until the railway closed in 1951.

After withdrawal it passed through several owners and display locations, including Gilltraps Auto Museum and Dreamworld. It was later returned to Rocky Point and restored for static display.

Since 2013 the locomotive has been preserved at the Beenleigh Historical Village and Museum.

Modern operations

Rocky Point is now one of the smallest operating sugar mills in Australia. The amount of cane available to the mill has declined substantially as agricultural land between Brisbane and the Gold Coast has come under increasing development pressure.

In 2016, mill owner David Heck stated that the district generally averaged approximately 250,000 tonnes of cane in a normal season, although favourable seasons could produce around 400,000 tonnes.

More recent production has generally been lower. Rocky Point crushed 194,936 tonnes during the heavily disrupted 2022 season and 215,874 tonnes in 2023.

In 2026, the Rocky Point district was reported to produce up to approximately 290,000 tonnes of cane annually.

Cogeneration

A 30 MW biomass cogeneration plant was constructed at Rocky Point during 2000–01 as a project involving W.H. Heck & Sons and the Queensland Government-owned Stanwell Corporation. The plant uses bagasse, together with other biomass fuels, to produce steam for the sugar mill and electricity for export to the grid.

The plant uses a 30 MW Alstom steam turbine and generator and began exporting electricity to the Queensland grid in 2002.

Ownership of the cogeneration plant subsequently changed. In January 2022, the mill owner purchased the cogeneration facility and undertook further expenditure intended to improve its reliability.

The cogeneration plant continues to operate as a registered generator in the National Electricity Market.

Ethanol production

An ethanol distillery was constructed at the Rocky Point site in 1990 and production commenced in 1991. The plant processed molasses produced during sugar manufacture into alcohol and formed part of efforts to diversify the mill beyond raw sugar production.

Rocky Point subsequently participated in projects aimed at increasing Australian fuel ethanol production, including receiving Commonwealth support during the 2000s for proposed expansion of ethanol capacity.

Recent operations and future

Rocky Point has experienced a number of difficult crushing seasons associated with mechanical reliability and wet weather.

The 2022 harvest did not begin until 29 October and continued until 5 February 2023. Only about half of the available crop was harvested, with the mill and cogeneration plant experiencing repeated breakdowns.

The 2023 season ran from 23 August until 19 December, during which 215,874 tonnes of cane were crushed at an average CCS of 13.48.

The 2024 season commenced on 31 July but was heavily disrupted by mill and cogeneration problems and persistent wet weather. Crushing ceased in December with only approximately 56 per cent of the estimated crop harvested.

Mechanical problems again affected the end of the 2025 season. Rocky Point was the final Queensland milling district still crushing in December, and operations were scheduled to resume after the Christmas shutdown in January 2026 to process the remaining cane.

Cane supply after 2027

In June 2026, W.H. Heck & Sons notified approximately 50 Rocky Point cane growers that their cane supply agreements would not be renewed after the 2027 crushing season. The existing agreements remain in force for the 2026 and 2027 seasons.

The announcement created uncertainty over the future of sugar milling at Rocky Point. Although grower representatives have described the decision as the forthcoming closure of the mill, governing director David Heck had not, as of August 2026, confirmed that the factory itself would permanently close.

CANEGROWERS and other industry organisations are investigating whether cane from the Rocky Point district could instead be transported approximately 100 kilometres to Condong Sugar Mill in northern New South Wales after 2027.

Transport

Rocky Point currently receives all harvested cane by road. It is one of the small number of Australian sugar mills without an operating cane railway.
