The Do’s and Don’ts of Classroom Behaviour
Since school is the place where you spend a good part of your day, it’s a good idea to have a few rules regarding classroom etiquette in mind.
To begin with, it’s always nice to greet your teacher and the other students when you walk into the classroom. If you go to class after the lesson has already started, it’s polite to apologise to your teacher. During the lesson, you need to respect your classmates, as well as your teacher. That means you should pay attention to others when they’re speaking to the whole class, and you shouldn’t talk to those next to you while the teacher is trying to explain something.
Of course, all this doesn’t mean that the classroom needs to be strict and boring. Your teacher will certainly appreciate it if you have something funny to share with the rest of the class. Also, if you have any fresh and creative ideas about a class project or trip, your teacher will be more than willing to hear about them. After all, teachers run out of ides too! Remember, teacher were once students themselves, and they know very well that every now and then, the class needs to do something different from their usual routine and, above all, they know that learning should be fun!

You should never talk when entering the class.
If you are late, you need to bring a note from your parents.
You should never talk in the classroom.
It’s OK to tell a joke in the classroom.
You should feel free to make any suggestions related to school matters to your teacher.

The rock art of Australia's Indigenous peoples is the oldest and richest in the world, dating as far back as 60,000 years and spread across hundreds of thousands of sites.[297] Traditional designs, patterns and stories infuse contemporary Indigenous Australian art, "the last great art movement of the 20th century";[298] its exponents include Emily Kame Kngwarreye.[299] During the first century of European settlement, colonial artists, trained in Europe, showed a fascination with the unfamiliar land.[300] The naturalistic, sun-filled works of Arthur Streeton, Tom Roberts and others associated with the 19th-century Heidelberg School—the first "distinctively Australian" movement in Western art—gave expression to a burgeoning Australian nationalism in the lead-up to Federation.[300] While the school remained influential into the new century, modernists such as Margaret Preston, and, later, Sidney Nolan and Arthur Boyd, explored new artistic trends.[300] The landscape remained a central subject matter for Fred Williams, Brett Whiteley and other post-World War II artists whose works, eclectic in style yet uniquely Australian, moved between the figurative and the abstract.[300][301] The National Gallery of Australia and state galleries maintain collections of Australian and international art.[302] Australia has one of the world's highest attendances of art galleries and museums per head of population.[303]
Australian literature grew slowly.[305] IN19th-century writers such as Banjo Paterson and Henry Lawson captured the experience of the bush using a distinctive Australian vocabulary. Their works are still very popular; Paterson's bush poem "Waltzing Matilda" (1895) is regarded as Australia's unofficial national anthem.[306] Patrick White and South African-born J. M. Coetzee were awarded the Nobel Prize in Literature in 1973 and 2003 respectively,[307] and Peter Carey, Thomas Keneally and Richard Flanagan are receipients of the Man Booker Prize.[308] David Malouf and David Williamson are also renowned writers[309] and Les Murray is regarded as "one of the leading poets of his generation".[310]
Many of Australia's performing arts companies receive funding through the federal government's Australia Council.[311] There is a symphony orchestra in each state,[312] and a national opera company, Opera Australia,[313] well known for its famous soprano Joan Sutherland.[314] At the beginning of the 20th century, Nellie Melba was one of the world's leading opera singers.[315] Ballet and dance are represented by The Australian Ballet and various state companies. Each state has a publicly funded theatre company.[316]
