No, Melbourne doesn't have rhinos that like to travel on skateboards (although if you do see one, beware!).
This is actually a Yarra Tram safety campaign to raise pedestrian's awareness of trams when walking near tram tracks. The Beware the Rhino campaign has proven to be very successful; the number of pedestrians involved in collisions with trams is down by 25% than the previous year so far.
Where I can see it? The picture of the rhino can be found near tram stops, on trams and if you would like to take a photograph with a huge poster of the rhino (and who wouldn't?) you can find it at tram stop 22 on tram route 1.
This sign makes me smile every time I see it (perhaps this should replace the previous sign to lift our spirits?).
The sign is located at Lakeside Drive and warns drivers to give way to swans that wander from Albert Park Lake to the golf course and back again.
The reason why I like this sign so much is that it makes no sense at all. How can the swan be crossing the road if he's in the water? And if he's enjoying a swim (which by the picture it seems that he is) why is there a warning? I believe there should be a sign next to this one showing the swan getting out of the water towards the road.
The swans know they have the right of way when they decide to cross the road and go back to the lake
