Please note: In many cases, the station position in our database is accurate
to only one minute. Thus, the tide gauge may not appear to be on the coast.
Station density along some sections of the Australian coast has meant that station codes 601 onwards have been re-ordered compared to those in earlier versions of the PSMSL data set.
