Hi,

The footway (way 1202026342 https://www.openstreetmap.org/way/1202026342#map=18/-37.86047/144.74936) is wrong... in that it crosses it self. While a human can understand it a computer makes hard work of it. 

See https://tools.geofabrik.de/osmi/?view=areas&lon=144.74859&lat=-37.85975&zoom=19&baselayer=Geofabrik%20Standard&overlays=duplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways%2Cduplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways

The 'duplicate segment' is the issue. What is required is a 'multipolygon relation' with 2 ways - and 'outer' alone the outside of the footway and an 'inner' along the inside of the footway.
