I am using Mapbox Offline Map in my app using MBTiles. Previously I was using shapefiles for creating offline maps. After searching a lot I am not getting Australian shapefiles.
But my friend referred this URL which contain all the layers of MBtiles of ".osm.pbf" format (not .shp format).
Is there any way to use ".osm.pbf" file in TileMill to create MBtiles file or a way to convert ".osm.pbf" file to ".shp" file and then use it in TileMill?
Specifically answering the question you could use
osm2pgsql to get the open street map into postgres.
From here you can use postgres to shape command line
pgsql2shp
Bear in mind - TileMill is going to generate a rastered image map tile / not a vector. Using the original protocol buffer format / pbf is a better place to start and then you can apply styles on the fly.
Have a look at this video for high level overview of vector maps https://www.youtube.com/watch?v=se2cd3BMYRY
We can use ogr2ogr to convert .osm.pbf to .shp file.
ogr2ogr -f "ESRI Shapefile" -skip CGK.osm.shp CGK.osm.pbf
