[GIS] How to best set up QGIS for GDA 94 zone 55 (Australia)

australiacoordinate systemqgis

I am looking for help on the best way to set up QGIS for GDA 94 zone 55.
(i.e. all the relevant settings etc.)[1.8 in lieu of 2.0]

Am working off Garmin GPS/GPX data in GDA/UTM format (I access this data in QGIS usually after dumping it in Garmin Base Camp) and want to finalise maps in the GDA 94 zone 55 CRS. I am using other ESRI/shapefile layers/data which are in GDA 94 zone 55.

Currently I am having issues with measure/buffers/grids/scales etc.
i.e. to make a 50m buffer on a layer I have to enter 50m as 0.0005 as buffer distance.
i.e. can't make grid at all in this CRS

Any help appreciated.

Please consider that the questioner [as a not for profit volunteer] does not have formal training in GIS and is currently learning QGIS "on the fly"… and so appreciates linear explanations/GUI solutions.

The questioner is extremely grateful for all the work of those contributing to QGIS/FOSSGIS/these question/answer forums etc.

If you have to enter the buffer values as 0.0005 this means it's not projected in the correct projection. All you need to do is save your layer out with that projection.
