Debra Lawrance replaced Vanessa Downing as Pippa Fletcher in 1990, however after her own departure in 1998, the show continued to use both actresses' likeness in flashbacks and photographs throughout the series, possibly the only television serial to do so.
Ray Meagher remains the only original cast member still on the show since its premiere in 1988. Kate Richie (Sally) and Norman Coburn (Fisher) received a Guinness World Record along with Meagher for being the longest-serving actors and actress in an Australian serial in 2001. Coburn left in 2003 after fifteen years, while Richie left in 2008 after twenty years on the show. Both have since been eclipsed by Lynne McGranger, who has held the role of Irene Roberts since 1992, and is now the longest-serving actress in Australian television history behind Meagher. Ada Nicodemou has also been on the show continuously for twenty years, since 2000, also overtaking Coburn and Richie.
Sheila Kennelly and Frank Lloyd, who played original characters Floss and Neville McPhee, were let go from the show when their contracts expired at the end of the first year, because the producers felt more time needed to be focused on the younger cast members. The producers did not tell them until the last minute, but both had already found out by reading about their character's departures in a television soap magazine. The Executive Producer at the time, said he hoped they could be brought back in future episodes as special guests, but this never occurred, with them only being mentioned by other characters from time to time. Ultimately, Sheila Kennelly did return in 2000, and has returned a few more times since. However, by this time Frank Lloyd had passed away, so the decision was made to kill his character off, and not re-cast (off-screen). The same thing happened to original cast member Helena Bozich, who after just four months was let go, because the producers wanted to focus more time on the other younger cast members. It was planned, however, that she would make a dramatic return some weeks later, but this never eventuated.
The only year to have not featured a "death" on this show, is 1994.
Since the late 90s, models with no acting experience had been principally cast to play the young characters in the show in a desperate attempt of getting views. This has been attributed to the criticism that the level of acting seen in the show has declined over the years.
