Presenter: Keith Treschman, Map Group and RGSQ Member

It is impossible to transfer a spherical globe to a 2-dimensional surface without some distortion. The choice of a projection depends on what the map maker wants in terms of accuracy of area, shape, distance, or direction. Some major projections are covered along with their advantages and disadvantages.

Springbrook Daytrip

To start RGSQ trips program for 2026, we have organised a daytrip to Springbrook on 20th March. Among other points of interest, we will visit Purling Brook Falls and Best-of-All Lookout.

Travel by comfortable coach for a tour of these locations. Pick up will be at Eagle Junction and Coopers Plains.

The geology of the plateaus of Springbrook, Lamington and Mt Tamborine is formed from lava flows emanating from Wollumbin (Mt Warning), now a volcanic plug in the Tweed Valley which we will see from Best-of-All Lookout.

Significant as a UNESCO World Heritage Area, the Gondwana Rainforests of Australia comprise the major remaining areas of sub-tropical rainforest in southeast Queensland and northeast New South Wales. The Springbrook National Park is part of the World Heritage Area in Queensland.

The coach will leave Eagle Junction (Bus Stop 27, Park Av, between Sydney St and Junction Rd) at 7.30 am, with a second pick-up at Coopers Plains (Brittain Park, Troughton Rd, opposite Sherrington St) at 8.00 am. Parking is available at both locations, either on-street or off-street (Brittain Park). The first pick-up is close to Eagle Junction rail station.

After the second pick-up, the coach will go directly to Springbrook (Purling Brook Falls) and then to other points of interest.

The return journey will drop off at both pick-up locations. Expect to return to Eagle Junction by mid-afternoon.

There will be stops at picnic areas for BYO morning tea and lunch, so remember to bring your own! Also, bring a water bottle, hat, camera, sunglasses, sunscreen and wind jacket.

Numbers: The trip is limited to 20 people.

Cost: $60 per person (members), $70 per person (non-members)

Registration: When registering, please indicate whether you want to be picked up at Eagle Junction or Coopers Plains.

Mt Coot-tha Botanic Gardens – African plant safari

9.30-10.30 Introductory presentation and BYO morning tea
10.30am - 12.30 pm guided walk.

Join us for an “African Plant Safari” at the Brisbane Botanic Gardens, Mt Coot-tha, one of the best collections of African plants in Australia. The walk will be initially downhill from the lookout, zigzag through the African zone, proceed via the Tropical Dome and finish in the Arid Zone and Cactus House. The visit will mostly be devoted to plants from southern Africa, together with a few species from Namibia, East & West Africa, the horn of Africa, Egypt and one offshore island, depending on time constraints. The visit will be guided by RGSQ member Charles Naylor, a trained volunteer guide at the Gardens, who has been leading this walk since 2022, based on his experiences while a lecturer at the University of Zimbabwe in 1983-85 and a member of the Tree Society of Zimbabwe.

Parking: The 3-hour visit involves self-drive to the Brisbane Botanic Gardens at Mt Coot-tha. On weekdays the Gardens are less crowded and participants can drive onto the ring road within the Gardens to park in one of the two areas adjacent to the Lookout, or near the National Freedom Wall (see map attached – the Freedom Wall is a 5-minute walk from the Lookout).
