  • Changes to Driver Licence Sanctions in Your CLSD Region
    Changes to Driver Licence Sanctions in Your CLSD Region In 2020, Revenue NSW introduced a hardship program focused on First Nations people and young people. As a result, the use of driver licence sanctions for overdue fine debt changed on Monday 28th September 2020 in some locations. How are overdue fines and driver licence sanctions related? If a person has overdue fines, their driver licence may be suspended. The driver licence suspension may be removed if the person: • pays a lump sum to Revenue NSW, or • enters a payment plan with Revenue NSW, or • is approved for a WDO. A driver licence suspension can be applied for multiple reasons, so even after being told that a driver licence suspension for unpaid fines has been removed, people should always double check that it is OK to drive by contacting Service NSW. Driver licence restrictions can also be put on interstate licences and cannot be removed easily. If you have a client in this situation, they should get legal advice. What has changed? Now, driver licence sanctions will not be imposed as a first response to unpaid fines for enforcement orders that were issued on or after 28 September 2020 to First Nations people and young people who live in the target locations. What are the target locations? Locations that the Australian Bureau of Statistics classifies as: • very remote, • remote • outer regional, and • Inner regional post codes where at least 9% of the population are First Nations People. Included target locations on the South Coast are the towns of Batemans Bay, Bega, Bodalla, Eden, Eurobodalla, Mogo, Narooma, Nowra Hill, Nowra Naval PO, Merimbula, Pambula, Tilba and Wallaga Lake.

  • Jellyfish Catostylus Mosaicus (Rhizostomeae) in New South Wales, Australia
    - MARINE ECOLOGY PROGRESS SERIES Vol. 196: 143-155,2000 Published April 18 Mar Ecol Prog Ser l Geographic separation of stocks of the edible jellyfish Catostylus mosaicus (Rhizostomeae) in New South Wales, Australia K. A. Pitt*, M. J. Kingsford School of Biological Sciences, Zoology Building, A08 University of Sydney, New South Wales 2006, Australia ABSTRACT: The population structure of the commercially harvested jellyfish Catostylus mosaicus (Scyphozoa, Rhizostomeae) was investigated in estuaries and bays in New South Wales, Australia. Variations in abundance and recruitment were studied in 6 estuaries separated by distances ranglng from 75 to 800 km. Patterns of abundance differed greatly among estuaries and the rank abundance among estuaries changed on 5 out of the 6 times sampling occurred. Great variation in the timing of recruitment was also observed among estuaries. Variations in abundance and recruitment were as extreme among nearby estuaries as distant ones. Broad scale sampling and detailed time series of abundance over a period of 2.7 yr at 2 locations showed no consistent seasonal trend in abundance at 1 location, but there was some indication of seasonality at the second location. At Botany Bay, the abun- dance of medusae increased with distance into the estuary and on 19 out of the 30 times sampling occurred medusae were found at sites adjacent to where rivers enter the bay. Medusae were found to be strong swimmers and this may aid medusae in maintaining themselves in the upper-reaches of estu- aries, where advection from an estuary is least likely. Variability in patterns of abundance and recruit- ment suggested regulation by processes occurring at the scale of individual estuaries and, combined with their relatively strong swimming ability, supported a model of population retention within estuar- ies.
