  • This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

  • The Fairway Basin is 1200 km long, but less than 200 km wide, and lies on the eastern slope of Lord Howe Rise above the New Caledonia Basin. Its three segments trend north-northwest, north and northwest, and probably formed by continental thinning related to break-up of Lord Howe Rise and the New Caledonia/Norfolk Ridge in the Late Cretaceous. Normal faulting, probable input of terrigenous sediments, and subsidence to bathyal marine depths, characterised the basin until a period of compression related to Eocene overthrusting on New Caledonia. This led to uplift of Lord Howe Rise and erosion of parts of it, reversal of faulting in the Fairway Basin, and some volcanism. By the Oligocene the area was in bathyal depths, and pelagic ooze and some turbidites were deposited. The basinal sequence is generally 2000-4000 m thick, with the older sequences concentrated in depocentres, and uniformly thick Cainozoic carbonates (500-800 m) capping them. The terrigenous sediments are probably partly non-marine in the Cretaceous, becoming marine in the Palaeogene. There is evidence of sedimentary diapirs in the depocentres, probably composed of mud rather than salt, which appear to be fed by Cretaceous early-rift sediments. A widespread, seismic, bottom simulating reflector (BSR) lies 500-600 m below the sea bed above the depocentre. The BSR has negative polarity typical of a diagenetic BSR, rather than positive polarity typical of hydrate deposits, but seismic modelling can explain this as due to a thin hydrate horizon lacking underlying gas. Overall, the broader geological evidence suggests that the BSR represents a gas hydrate. If this is a hydrate, it is unusual in that it occurs in organic-poor rather than organic-rich sediments, suggesting that any gas may be thermogenic. Attempts to sample gas bleeding off any gas hydrates, by taking seabed cores above diapirs and apparent gas escape structures, have recovered very little gas. The gas composition suggests a thermogenic origin, but the results are equivocal. Much deeper coring for gas, or direct sampling near the BSR, could lead to better understanding of the hydrocarbon potential of this large, deepwater sedimentary basin.
