Overall, Canada's exports fluctuated considerably and reached a peak in 1988, while Australia's exports showed a downward trend. In contrast, the European Community experienced an overall increase and became the largest exporter by 1990.

In 1985, Australia exported 15 million tonnes of wheat, compared with 19 million tonnes in Canada. Australia's figure rose slightly to 16 million tonnes in 1986 before falling steadily to 11 million tonnes in 1989 and 1990. Meanwhile, Canada's exports decreased to 17 million tonnes in 1986, then increased sharply to a peak of 25 million tonnes in 1988.

In contrast, Canada's exports dropped dramatically to 14 million tonnes in 1989 before recovering to 19 million tonnes in the final year.

Overall, the process involves several stages, beginning with coal and oxygen entering a furnace and ending with electricity generation. Electricity is produced twice: first by a gas turbine using purified syngas and then by a steam turbine powered by steam created from waste heat.

Initially, coal is transported into a furnace, where it is combined with oxygen. Inside the furnace, coal is converted into raw syngas, while slag is removed from the bottom as a by-product. The raw syngas then passes through a removal unit, where impurities such as carbon dioxide (CO₂), mercury and sulphur are extracted. After purification, the clean syngas is sent to a gas turbine, which drives a generator to produce electricity.

Next, the hot exhaust gases from the gas turbine are directed to a heat recovery steam generator. There, the waste heat is used to produce steam. This steam powers a steam turbine connected to another generator, generating additional electricity. Finally, the electricity produced by both generators is supplied to the power grid, while flue gases are released from the heat recovery unit.

Overall, the percentage of school leavers who got a job increased over the period and became the largest group in 2000. In contrast, the proportion of students who continued further education decreased. Meanwhile, unemployment was the smallest category in all three years.

By 1990, the proportion of employed students had risen significantly to 50%, overtaking further education, which dropped to 38%. The unemployment rate also increased slightly to 12%.

In 2000, employment continued to rise and reached 55%, the highest figure shown in the charts. By comparison, the percentage of students choosing further education fell a little to 37%. At the same time, unemployment decreased from 12% to 8%, making it the lowest figure among the three categories.

Overall, the park has changed a lot. Some old features, such as the entrances and one rose garden, are still there, but many places have been replaced with new facilities.

There were three rose gardens, two at the top and one at the bottom left. In the top right corner, there was a pond for water plants, while a glasshouse was in the bottom right corner. Seats were also placed around the park.

Today, the fountain has been replaced by a rose garden with seats around it. The stage has become an amphitheatre for concerts. On the right side of the park, the pond and the glasshouse have been removed. A café and a children's play area have been built in the top right, while a water feature is now in the bottom right. In addition, an underground car park has been added with an entrance from the east side of the park.
