ogrpolygonqgis
I am using QGIS.
I have polygon feature and want to be able to generate points inside it. I need this for one classification task.
Generating random points until one is inside the polygon wouldn't work because it's really unpredictable the time it takes.
What about from the processing toolbox where there's a tool called Random points along line.
You can also set the minimum distance.
I would guess that your polygon layer originally was not saved with the EPSG:28356 CRS but that you set it manually.
Most likely the polygon layer was orignally saved with another CRS using degrees as units.
I did a quick test using polygons with a CRS of EPSG:4326 (i.e. using degrees as units) and using your exact parameters for the Random Points Inside Polygons (Fixed) tool:
I then right-clicked the Polygons layer, chose the Save As... option, assigned a new CRS which uses meters (i.e. EPSG:28356) and again repeated the same steps. This is the result:
So try saving your polygon layer into a new shapefile with the relevant CRS and run the tool again.

Start by decomposing the polygon into triangles, then generate points inside those. (For a uniform distribution, weight each triangle by its area.)
