What comets were seen over the last 5 years?
Some comets that have appeared in the last 25 years are Hale-Bopp, Hyakutake, Shoemaker-Levy 9, Swift-Tuttle, and Tempel 1. C/2006 P1 McNaught was the brightest comet in the last 25 years.
how often do comets come near the sun?
It's almost impossible to give a definitive answer. Some comets only have short orbital periods (less than 300 years), while others have been calculated to take thousands of years to return close to the Earth ! As an example, Halley's comet returns roughly every 76 years (last time was in 1986, the next time will be around 2062). At the other end of the scale, comet McNaught is estimated to take around 92,000 years to travel once around the sun !
How many years does it take for Halley's comet to come to Earth and when is it next due to pass?
There are comets visible from Earth many nights, they are just too faint to be seen easily. So, there is a continuum of brightness -- comets from very faint to quite bright. The brightest are the spectacular ones that get in the news. Also, bright ones may be discovered not long before they are visible. If I remember correctly, McNaught, of January/February 2007, the second brightest comet since 1935, was discovered about 6 months before it came close.
What is the name of the comet that supposedly appears every 2000 years or so and was last seen in the mid 90's?
"Periodic" comets reappear at predictable intervals, such as Haley's Comet. Some comets are never seen again. A few crash into the Sun and are destroyed; a few crash into other planets, such as the Shoemaker-Levy comet that hit Jupiter. Many comets have such long periods, in terms of thousands of years, that no records exist that anyone ever saw them before.
When was the last time that Lamington erupted?
If you are of the belief that the world has been around for millions of years, then the last time Lamington erupted is believed to have been 20 million years ago. There has been no volcanic activity on the Australian mainland for at least thousands of years.

When was the loch ness monster spotted?
The Loch Ness Monster has been spotted many times over the last 200 years. Whether these have been genuine sightings, optical illusions or mis-interpretations of something floating semi-submerged, is a matter of sometimes heated discussion. There have been a few genuine scientific surveys using sonar equipment but there has been no unequivocal proof, one way or the other.
