The signatures on the petition were mainly collected at two events that were held in Marrickville during April and May 2018. These events were the Anzac Day Reflection held on 25 April 2018 in Richardson’s Lookout – Marrickville Peace Park and the National Sorry Day Walk along the Cooks River via a number of Indigenous Interpretive Sites on 26 May 2018. The purpose of the petition is to creatively showcase the history and culture of the local Aboriginal community along the Cooks River and to publicly acknowledge the role of Pemulwuy as “father of local Aboriginal resistance”. The action petitioned for was expressed in the following terms: “We, the undersigned, are concerned citizens who urge Inner West Council in conjunction with Council’s Aboriginal and Torres Strait Islander Reference Group (A&TSIRG) to designate the walk between the Aboriginal Interpretive Sites along the Cooks River parks in Marrickville as the Pemulwuy Trail and produce an information leaflet to explain the sites and the Aboriginal connection to the Cooks River (River of Goolay’yari).” A total of 60 signatures have been collected on the petition attached.

Reproduction for purposes other than those listed requires permission from Sydney Water. Sewage Treatment System Impact Monitoring Program | Vol 1 Data Report 2019-20 Page | i Executive summary Background Sydney Water operates 23 wastewater treatment systems and each system has an Environment Protection Licence (EPL) regulated by the NSW Environment Protection Authority (EPA). Each EPL specifies the minimum performance standards and monitoring that is required. The Sewage Treatment System Impact Monitoring Program (STSIMP) commenced in 2008 to satisfy condition M5.1a of our EPLs. The results are reported to the NSW EPA every year. The STSIMP aims to monitor the environment within Sydney Water’s area of operations to determine general trends in water quality over time, monitor Sydney Water’s performance and to determine where Sydney Water’s contribution to water quality may pose a risk to environmental ecosystems and human health. The format and content of 2019-20 Data Report predominantly follows four earlier reports (2015-16 to 2018-19). Sydney Water’s overall approach to monitoring (design and method) is consistent with the Australian and New Zealand Environment and Conservation Council (ANZECC 2000 and ANZG 2018) guidelines.

  • Measurements of Snapping Shrimp Noise Along the Cooks River, Sydney
    Paper Number 91, Proceedings of ACOUSTICS 2011 2-4 November 2011, Gold Coast, Australia Measurements of Snapping Shrimp Noise along the Cooks River, Sydney Marshall V. Hall 9 Moya Crescent, Kingsgrove, New South Wales 2208, Australia ABSTRACT The Cooks River is a 23-km meandering urban waterway of south-western Sydney, and empties into Botany Bay. The tidal section is around 11 km long and supports significant numbers of mangroves, birds, and fish. Due to the tides, the salinity fluctuates but falls off slowly with distance upstream. Underwater ambient noise has been measured from 18 bridges over the lower 12 km of the river. Apart from occasional traffic noise that transmits into the river from some bridges, the only sounds heard underwater have the characteristics of (saltwater) snapping shrimp. The Peak Sound Pressure Level of the strongest snaps is in the neighbourhood of 180 dB re 1 Pa2 at positions up to 3 or 4 km upstream from the river mouth, but then falls steadily as the measurements are repeated further upstream, al- though a previous survey of snapping shrimp distribution with a dipnet found a population 9 km upstream. The pre- sent finding is however consistent with previous findings for benthic life generally, which suggests that the snapping shrimp distribution may be limited by available food. The quieter sounds upstream are due to propagation of sound from the shrimp within 4 km of the mouth rather than more local shrimps, even though there are three 90-degree bends in the river course upstream of 4 km. Previous work has found that much of the riverbed is mostly sand, and should thus be a good reflector of sound.
