Hi Manish,
Welcome to the world of fishing...and welcome to Fishing Reminder.
As the name implies, you can use the Solunar clock to predict the best days and times. You can use email settings to get email reminders.
As for location, I have never been to Tassie. Looking on the map, maybe Errol Flynn Reserve and Short Beach on Marieville Esplanade at Battery Point might be a good choice for a first ever fishing trip. It has what looks like a good beach / sand area. A small creek at the north end. To the south and across the road, is a jetty and what looks like a boat ramp. The small headland looks like it is man made and quite rocky.
So there is creek, sand (beach), jetty and rock fishing all within walking distance. By the looks of it, a pretty good location for a first time ever fishing trip.
Let us know how you go
