Although not called Tregony at that time, the area was of great interest to early explorers. The Darling Downs was seen as having great agricultural potential but initial access to the area was via an overland route through inland New South Wales, which would create an unreasonable time and cost barrier for trade. A faster route was needed to the coast, preferably via the newly developing towns of Ipswich and Brisbane, which were linked by the Bremer and Brisbane Rivers to Moreton Bay and then by sea to other parts of Australia and overseas. However, the Great Dividing Range separated the Darling Downs from the coast. On 11 June 1827, Allan Cunningham approaching from the Darling Downs identified a possible dray route (later known as Spicer's Gap) across the range. On 21 August 1828, travelling from Ipswich, Cunningham found a second pass, now known as Cunningham's Gap, but he thought (wrongly) that it was the same pass as he had found in 1827, but Cunningham's Gap is about 4 km north of Spicer's Gap. Cunningham reported to the New South Wales Government that the route should be via Cunningham's Gap.
