Each year in September, a group of volunteer ‘platy-watchers’ gathers before sunrise at the Brookfield Showgrounds prior to heading off to observation posts on Moggill and Gold Creeks.  They spend an hour or so at their appointed site then return to the Showgrounds to deliver their results and share a BBQ breakfast provided by MCCG.

The Annual Platypus Survey began in 2005 and is entirely volunteer-driven. Since the survey began, sightings have fluctuated but happily this unique species is still living in Brisbane’s back yard.

Snapshot over the years:

• 2018        7 platypus sightings across the catchment
• 2017 15 platypus sightings in total, of possibly 12 individuals

2016 11 platypus in total; some in new spots from previous years

• 2015 11 platypus, most on lower reaches of Moggill Creek and mid-Gold Creek

• 2014 9 platypus, similar to 2013. Platypus reported in less disturbed areas of the creeks

• 2013 (another wet summer, but dry late winter): 7 individual platypus seen

• 2012 (wet summer, but 7 weeks without rain prior to survey): 17 individual platypus seen

• 2011 (severe flooding of creeks early in year): 13 individual platypus seen

• 2010 (continuing good rains): 20 individual platypus seen

• 2009 (severe flooding of creeks early in year): 7 individual platypus seen

• 2008 (10-year drought broken, good rain, water in the creeks) 15 individual platypus seen

2005-2007 (extreme drought years): maximum of 6 individual platypus seen.

The following graph shows how sightings have fluctuated over the years we have been doing the snapshot surveys:

2016 Survey Report – Sunday 11 September:

• • We had an amazing number of 71 volunteers dispersed along Gold and Moggill Creeks.
  • Our survey results yielded 11 platypus sightings in total, with platypus seen across a broad spatial scale:
    • Two recorded at one site at Branton Street, Kenmore and a total of three animals seen in this section (exciting ! We haven’t seen this many platypuses for a few years.)
    • Sightings in Moggill Creek and Gold Creek in Upper Brookfield, near Brookfield Produce, in the Huntington Estate, near Kenmore High School and in lower Moggill Creek in the Kilkivan/Manyung streets area.
    • A platypus seen close to the Gold Creek dam on Gold Creek. (They haven’t been seen that far up the creek since the refurbishment of the wall back in 2005).
    • The creek habitat assessments were similar throughout the catchment’s survey sites. Most were fair to good, with only two records of very poor quality habitat.

2015 Survey – key points:

• • • Platypus are persisting in lower Moggill Creek, despite its urban environment
    • Number of platypus sightings was low in upper Moggill Creek
    • Platypus have returned to two sites in upper Gold Creek where they haven’t been observed for several years
    • This is a snapshot survey on one morning. We know there are platypus in some sites where they weren’t observed this time
    • We don’t know if a couple of sightings in close proximity were the same animal or two individuals. We also don’t know if there are any breeding pairs

2013 Survey Report:

In 2013 the sightings (with one exception in Upper Brookfield) were all in lower Moggill Creek. This is a higher density urban area of the catchment that has been the focus of tireless community riparian restoration efforts led by MCCG volunteers such as Malcolm Frost, Bryan Hacker and Damien Egan over many years. Perhaps the continual presence of platypus in these areas is in no small part due to their dedication to conserving the area’s biodiversity.

Why was the number of platypus observed lower in 2013 and why were none seen in Gold Creek, a former platypus stronghold? There is no simple answer, but factors may include:

• • • Little recent rainfall and therefore generally less water and flow in the creeks, meaning that platypus are currently concentrated in restricted ‘stronghold’ areas.
    • Since the surveys began, Gold Creek has been subjected to controlled water releases from the Gold Creek Dam (including flooding and complete cessation of flow) and major disturbance during dam wall reconstruction. Perhaps platypus numbers in this creek have been declining as a result.
    • Platypus were there but simply were not seen at the time of the survey. We know from reported sightings from local residents that they are being regularly observed at some of the stronghold sites where they weren’t seen on the survey morning.

The first Kids’ Day at the Cottage was held in 2010 and has since become a very popular annual event.  It is usually held on the last Sunday in May. All activities are FREE for children thanks to volunteer expert presenters and workers, plus support from the Lord Mayor’s Suburban Initiative Fund for the Pullenvale Ward.

Presenters offer activities for young people that engage, entertain and inform on some aspect of our local environment and its biodiversity. The adults with them also find out more about the Cottage, the MCCG and its activities.
