Crocs are very sneaky. Just because you can't see them it's best to be aware .that they could be sizing you up as their next meal. The crossings mentioned are especially dangerous fishing spots.
I always try to ensure neighbours can access their property easily when I park. However I live in a country town where driveways are usually more generous
We see them often as we live near a beach. Most times they will fear you and slither away. It's illegal to kill them. However I know that some in our street have "disappeared". We are constantly on lookout to protect pets in warmer weather.
